iTunes won't open/quits unexpectedly

[KikoNoUdon]

I restarted my computer a few days ago because safari froze up on me. When my Macbook Pro finished rebooting I tried to open itunes. It didn't even open before a message came up saying "Itunes quit unexpectedly."
I've tried restarting my mac, repairing disk permissions, reinstalling itunes, and all to no avail. The error report looks like this:

You might try booting from your OS X install disc, then after selecting your language, click Tools >> Disk Utility in the menu at the top. Do Disk Repair and verification, maybe even run it a couple of times. Then do permissions repair again, close disk utility, restart the system,a nd see if that helps.
