I also saw my Apple Menu Options Prefs file become corrupted. my system did not crash, but the contents of the Apple Menu Items Folder kept randomly changing for a while. it was one of the strangest behaviours I have seen. every time I went to the Apple menu it contained different things. after I trashed the prefs file it immediately went back to being screwed up as soon as I opened the Apple Menu Options CP again. I had to really erase (using the Secure Delete util that came with StuffIt Deluxe) the prefs file for it to not screw up again. it didn't ever crash though.
