QuickTime 7.6 randomly crashing

[treichert]

Yesterday QuickTime started crashing really randomly and sometimes after just 3 minutes of playback or less. It seems to happen more easily with MKV files (Perian) but also happens with MOV or AVI files.
I already rebooted and repaired permissions and I included the crashlog (only the crashed thread).

Would be great if someone had any idea what this is about....any help is definately appreciated.
