IPhoto won't open after crashing in edit screen

Question

MacBook Pro v. 10.5.8
iPhoto v. 8.1.2
I was flipping through photos and editing them with the crop feature selected. I pressed the arrow key to go to the next photo (still in edit screen) when iPhoto crashed. The wheel kept turning and it was frozen. I did Force Quit, and since then the program won't open. I tried reinstalling 8.1.2 again--still no luck.
I don't know what parts of the error message would be helpful, but here's the first bit:

Answer 1

As a Test:
Hold down the option (or alt) key and launch iPhoto. From the resulting menu select 'Create Library'
Import a few pics into this new, blank library. Is the Problem repeated there?
