Hi Joar,
Yes, I'm creating my own thread in-order to update the UI while
importing process is going on (like iTunes). The problem is appearing
every time once the importing process is over.
Here is another variant of crash:

I am getting a crash with my application (universal binary) on

This application basically imports svg files and renders them on

I've tried by setting different environment flags
(NSZombieEnabled, MallocStackLogging etc), but not able to figure
out the problem.
It's crashing while you have a save panel open, but in a background
thread that doesn't seem to be yours? A crash in objc_msgSend often
indicates a memory management error of some kind.
Do you create any threads yourself? Are you doing anything in these
threads that might not be thread safe? Is this problem easy to
reproduce?
