iPhoto ’09 might unexpectedly quit when you export photos in OS X Mavericks 10.9.2 or later. This can happen if you're exporting photos that you imported from an iPhone, iPad, or iPod touch with iOS 7.
To resolve this issue, try the export again. When you get to the Export dialog, select either Original or Current from the Kind drop-down menu.
Original will export the original unmodified images.
Current will export the images with current edits included.
