IPhoto won't open 9.4.2 and OSX 10.7.5

Question

I'm not sure about when this happened, but I can no longer open iPhoto.  It goes to an error log that says "iPhoto Unexpectedly Quit".
Incidently, my Displays, Clock and Icon in the tool bar no longer show up either.
I've tried reinstalling the 10.7.5 update, reinstalling iPhoto, Command+Option at startup of iPhoto, repairing permissions (always shows fixed permissions, never got it to come back clean), repair disk to no avail.
Here is the first 30 or so lines from the log.
Anyone have any ideas? 
This is on a Mac Pro 2.66GHz.
Thanks,
Mike

Try trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder.
(On 10.7: Hold the option (or alt) key while clicking on the Go menu in Finder to access the User Library)
(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.
