Does it work when started in "Safe Boot" (hold down Shift from power on all the way to the desktop)?

[Jimwh]

No difference when opening in Safe Boot...

[dnanian]

I think I'm going to have to suggest that you reinstall iPhoto, Jim. If that doesn't help, archive-and-install the OS.

[Jimwh]

will do...Thank you. Just curious, was there anything in the crash/console logs that point out an issue?

[dnanian]

Nothing terribly useful in there, no. It's crashing deep, deep inside iPhoto, in something like the 18th thread...

[Jimwh]

Researching further, I found that rebuilding the library by invoking Cmd & Option when opening the library and then selecting all options appears to have worked. For reference, you can refer to http://support.apple.com/kb/HT2638 from Apple's Support site.

Many thanks for your assistance.
