Photo Booth freezing/crashing Mavericks OS. How can I fix this?

Question

I downloaded Mavericks via Apple on November 5.  Before installing it I made sure my Mac system was totally functional: ran disk repairs, checked if I had installed apps that wouldn't run in Mavericks, etc. Everything went well during installation, and I was able to use my laptop for two days UP UNTIL I tried to use Photo Booth! I got a message that Photo Booth was gathering my images (presumably to move it to a new location based on new configuration of Mavericks), and there was also a progress bar. Suddenly I realized that the progress bar would not advance and that my MacBook Pro (mid 2007) had frozen. I restarted it, only to have it freeze upon startup.  I tried resetting the PRAM, and that only allowed me to make it to the desktop, but with no visible hard drive on my desktop, no dock at all, and I couldn't access any of the menus in the Finder window, not even to restart or shut down. Then I tried several options:
Hard reset and tried to boot in safe mode. NOTHING. It was just impossible to safe boot it. At times I'd get up to half of the progress bar and then it'd freeze. Hard reset Command + S
Hard reset Command + V
Hard reset and reset the PRAM again, etc.
Eventually I'd  make it to the desktop, the dock would show up, also the files on my desktop, but it'd not take longer to freeze again. It was all very odd because there was always a point when it'll would just freeze.
Then I decided to try Command + R to repair disks. I Verified and repaired the discs. Then I restarted, and it froze. I decided to reinstall the OS through the Recovery mode screen. I did it. No success the problem persisted. I redid all this last steps again: Command + R, verify/repair disks, reinstall OS X. Once completed: MBP froze. The whole process was so time consuming that I gave up and just turned off my computer. The next day I was able to turn my computer on with success. Some of the folders that were open before the Photo Booth crash were on open. I closed everything and turned my MPB off using the Finder menu. Then I turned it on again, and once I got to the desktop and found no folders open, and I reopen Safari because I remember I was using it before opening Photo Booth. To my surprise it opened and all the pages I was visiting before the crash were there as if Safari resumed just how it was before the crash. I turned it all off again using the Finder menu. I was wondering if those Safari and the folders that were left open were for some reason conflicting with the system's start up. Then I turned it on again and this time I proceed to work with my computer but not before verifying/repairing the disks through the System Preferences menu.
Everything went well. Later that day I decided to open Photo Booth to see if it'd work smoothly. It didn't open very smoothly but I was able to play around with it for a while. I turned it off and everything was great. The system was a little slower than what I was used to but I guessed it's because Mavericks demands a more advanced hardware. Then the next day the problem restarted!!! I was able to get to my desktop normally and decided to open Photo Booth to complete the task I wanted it to use it on the day of the first freeze/crash. And it froze my computer and it all restarted. This time, even redoing all the steps and even after reinstalling the system 3 times, I still can't get my computer to work. But at least one thing I know: this problems is being caused by Photo Booth! I'm desperate and I don't want to format and do a clean install because I will lose some important files. Does any of you have ANY idea of what's going on and what can I do to fix this? It's unnerving to have it fixed once (not knowing how) and suddenly find myself dealing with the same problem again!

Answer 1

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter the name of the crashed application or process in the Filter text field. Select the messages from the time of the last crash, if any. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V).
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
In the Console window, look under User Diagnostic Reports for crash reports related to the crashed process. The report name starts with the name of the process, and ends with ".crash". Select the most recent report and post the entire contents — again, the text, not a screenshot. In the interest of privacy, I suggest that, before posting, you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if it’s present (it may not be.) Please don’t post other kinds of diagnostic report — they're very long and not helpful.
