IMac (Intel) locked up during iPhoto session

Question

My wife was working between iPhoto and Photoshop Elements 9. After migrating edited photos, she was viewing them in iPhoto fulluscreen when the cursor disappeared and the computer basically locked. I would not respond to mouse or keyboard (both wireless) input. Could not perform 'Force quit'; ended up doing a power button shutdown and then restart. The following is the last part of the console message log including the point where the computer locked and the subsequent restart:

The mac is a 3.5 year old 20" Intel iMac, core-duo, 4 gb ram, with a 500 mb hd. We have had issues with the mac 'freezing' in the past, but not recently. If anyone can shed light on the cause, or point me in the right direction, it would be greatly appreciated.

Hello Agaber
Try to force quit the application with the steps in the article below. You also may have to gold the power button down for about 10 seconds to force your iMac to power off.
