IPhoto - crash on startup on brand new mac mini

Question

Hi
Just bought a new Mac Mini, ran migration assistant to move all my files over to the new machine.  My iPhoto library is stored on an external hard drive.
Every time I launch iPhoto on the new Mac, it immediately crashes.   The first 30-40 lines of the crash report is below.  I have deleted and reinstalled iPhoto with and without the external hard drive connected, no change in result.    Any advice would be appreciated.

Answer 1

Try reinstalling iPhoto from the App Store.  You may have to move iPhoto to the Trash bin in the Dock (but don't empty yet), go to the App Store and download and install it again.
If that doesn't help you'll need to boot into the Recovery volume (boot with the Command + R keys held down) and reinstall the system.
Lastly you have 90 days of free phone support from Apple so if all else fails call them.
