IPhoto '11 keeps crashing when trying to import to library

Question

Hello,
May I ask for some assistance please. For some reason tonight when I open iPhoto and try to import photos it keeps crashing. I was able to import about 30-40 photos from a CD before this started to occur. I have included the crash log below. Grateful for any advice?
Mike

Answer 1

It might be another preference file other than iPhoto's so here's how to determine if that's the case:
Trouble Shooting Preferences
NOTE: In Lion and Mountain Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder.
1 - close all applications.
2 - open your Home/Library folder and Option-drag (copy) the Preferences folder to the Desktop. 
3 - select the contents of your Home/Library/Preferences folder and drag them into the Trash bin in the Dock.  You will be asked to provide your Admin password.
4 - reboot.
5 - run the application again and determine if the problems is fixed
6 - If the problem is fixed:
A - open the working Home/Library/Preferences folder.
B - Open the Preferences  folder on the Desktop, select all of the contents and drag them into the working Home/Library/Preferences folder.
C - When the Copy window pops up check the "Apply to All" check box and then click on the Don't Replace or Skip button.
D - reboot.
7 - If the problem is NOT fixed, drag the contents of the Preference folder on the Desktop into the Home/Library/Preference folder and replace the entire contents that were created by clicking on Replace.
8 - reboot.
