I found the problem. Buffer overrun in one of my threads. I was stomping on the other threads memory and things were going kablooey all over the place. :)

I am simply throwing up a save panel and doing a runModal on it. I'm not doing anything fancy at all. I am getting a lot of crashes (not always) in:

The crashes that are not in this method, where do they pop up?

I hope you got the Monty Python reference? :-)

Could you show a bit more of the backtrace btw.?

Any ideas what could be causing this? The app is multithreaded. However, I have been careful to do all gui operations only in the main thread. That said, this call to NSSavePanel is done in a method that is called with performSelectorOnMainThread:withObject:waitUntilDone:

waitUntilDone: TRUE is used of course.

Why "of course"? Is the other thread going to do anything with the data returned from the save panel?
