IPhoto quits unexpectedly and won't let me access photos

Question

My iPhoto program has just started acting oddly; when I hook up a camera or my iPhone, it won't start up; just quits. And if I start it up from the computer, as soon as I click on a photo or album title or caption, it quits. I am using the latest version of iPhoto, 8.1.2
Coincidentally, my Safari is also problematic; any time I access a page with requiring a password it quits if the "prefill" option is used. Firefox works fine. Help!

Try this basic fix: trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder. (Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
*What's the plist file?*
For new users: Every application on your Mac has an accompanying plist file. It records certain User choices. For instance, in your favourite Word Processor it remembers your choice of Default Font, on your Web Browser is remembers things like your choice of Home Page. It even recalls what windows you had open last if your app allows you to pick up from where you left off last. The iPhoto plist file remembers things like the location of the Library, your choice of background colour, whether you are running a Referenced or Managed Library, what preferences you have for autosplitting events and so on. Trashing the plist file forces the app to generate a new one on the next launch, and this restores things to the Factory Defaults. Hence, if you've changed any of these things you'll need to reset them. If you haven't, then no bother. Trashing the plist file is Mac troubleshooting 101.
