IPhoto crash + photostream issues

Question

I'm having a ton of issues with iPhoto after getting a new computer. Everything moves really slow (i've emptied the trash and restarted both the program and my computer), i'm unable to launch photo stream, etc.
Following is the crash report. Any suggestions?

Answer 1

Does iPhoto run OK if you turn off Photo Stream?  How many photos are in the PS? If there's a lot it may take a while for all to get downloaded.
Although a long shot try the following:
1 - delete the iPhoto preference file, com.apple.iPhoto.plist, that resides in your
     User/Home/Library/ Preferences folder.
2 - delete iPhoto's cache file, Cache.db, that is located in your
User/Home/Library/Caches/com.apple.iPhoto folder (Snow Leopard and Earlier).
or with Lion and Mt. Lion from the User/Library/Containers/com.apple.iPhoto/
Data/Library/Caches/com.apple.iPhoto folder
3 - reboot, launch iPhoto and try again.
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.
