Finder keeps crashing randomly
For some reason, Finder has been crashing randomly for one week.
Every five minutes or so, Finder closes for 10 seconds, and reopens again. Every time, I get a lot of error reports in Console:
(this is all in the same second)
01/05/2012 19:13:02.164 Finder: ISGetIconFamilyFromStorage: seed mismatch for 22630019, actual seed is 62bbd95a
01/05/2012 19:13:02.165 Finder: ISGetIconFamilyFromStorage: seed mismatch for 2233001a, actual seed is 436c6125
01/05/2012 19:13:02.165 Finder: _GetISImageRefFromIconRefInternal: could not retain image ref 0x27b70021 (err=-2580)
Each of these appears about 20 times with random numbers. I've tried deleting com.apple.finder.plist and quitting Finder, but it keeps happening.
Any help?
