random error opening blank compopsition

I keep getting random errors when i open a composition in QC (not always). I thought I fixed one composition (which was giving similar errors) since I havent got an error in the last 2 days, but today, opening a new blank composition at start up I got this:

0x938cc8a7: -[NSCarbonMenuImpl performActionWithHighlightingForItemAtIndex:] 0x938cc4ef: -[NSMenu performKeyEquivalent:] 0x938cad94: -[NSApplication _handleKeyEquivalent:] 0x937e7ac7: -[NSApplication sendEvent:] 0x0000e41d 0x93744fe7: -[NSApplication run]

the errors I got before where similar, but a little longer... I do not have a copy of the text know, but if i get them again I will post them with the qc comp.

Any help will be greatly appreciated... I actually reinstalled the system and the developers package trying to fix this. Maybe is a plug-in what is causing this?

thanks

OK

I just opened again a brand new blank and got this
