Long story short... Installed, Reinstalled and Uninstalled iPhoto. Everything from versions 8.0 to 9.5.1.
None work... v8.0+ says need a newer version, v 9.5.1 just crashes at startup.
And obviously all the basics of booting, rebooting and all that good stuff. At the moment, the app is back at its initial state were the problem began 9.5.1.
Don't know if this helps, but here is the report that pops up when it crashes:
