My iPhoto keeps crashing after installing the latest update, can't do anything!

Question

My iPhoto keeps crashing after installing the latest update, can't do anything! It used to crash when importing but now I'm at the point where I open the software and after 2 seconds it crashes (nothing connected either). What to do? Can't access any photos

Answer 1

Try this:  launch iPhoto with the Option key held down and create a new, test library.  Import some photos and check to see if the same problem persists. If you can create a new library and import some test photos then the problem lies with your original library. 
If that's the case make a temporary, backup copy (if you don't already have a backup copy) of the library and apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Select the options identified in the screenshot. 
Fix #2
Using iPhoto Library Manager  to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next  window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
If iPhoto crashes while trying to create a new library then try this:
Make a temporary, backup copy (if you don't already have a backup copy) of the library and try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
     User/Home()/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
     User/Home()/Library/Caches/com.apple.iPhoto folder.

3 - launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding down the Option key when launching iPhoto.  You'll also have to reset the iPhoto's various preferences.
If that fails to help a reinstall of iPhoto is indicated. To do so you'll have to delete the current application and all files with "iPhoto" in the file name with either a .PKG or .BOM extension that reside in the HD/Library/Receipts folder and from the /var/db/receipts/  folder,

Then install iPhoto from the disk it came on originally and apply all relavant updaters.
P.S.  If you're still running Tiger, 10.4.6, then the above may not apply.  If you're running a newer system you should update your profile so we have a better idea of where you're at.
