Issue: iPhoto crashing when showing slide shows

Description: Some iPhoto users are having troubles with the program crashing when attempting to view slide shows as described in this Apple knowledge base article (http://support.apple.com/kb/HT2638).

Gregory Davis-- "iPhoto 09 works fine until I click the slide show button. As soon as I do this, crash and burn baby. It brings up the first picture from the event I've chosen and shows the title but then crashes before anything else happens. I've tried running OnyX and repairing all disk permissions, as well as running all the cleanup scripts. Nothing seems to fix the crashing."

This problem seems to be related to display resolution problems and specific monitor setups. In the past, people have had troubles with the built-in photos screensaver when running dual monitors after updating the iLife media browser.

This problem could be related since many of those affected have dual-monitor setups. Video driver conflicts with the iLife media browser could be the culprit, and while updates for either drivers or the iLife Media Browser will be needed for these problems to be properly addressed, temporarily modifying the display settings may help clear the issue.

Things to try:
1. Toggle resolutions In some instances, people have been able to change display resolution to a low value, such as 800x600, and run the iPhoto slide show without problems. Then upon resetting the display to standard resolution, everything still works fine.

2. Mirror displays Likewise, people with multiple displays have also been able to change the display settings to be mirrored instead of an expanded desktop, which has allowed the slide show to run properly even after resetting the display settings.

3. Rebuild libraries In some instances this could be a problem with corruption in the iPhoto library, and people can try rebuilding the library using the built-in maintenance tools in iPhoto. To access these tools, users should launch iPhoto and immediately hold the options and command keys to bring up the Rebuild menu. Users can try selecting various library components to rebuild, and then click "Rebuild" to start the process, which can take some time for large libraries. Users can also manually rebuild their libraries by following the instructions in this Apple knowledgebase article. (http://support.apple.com/kb/HT2638)
