While doing this, everything works fine, but in not determinable circumstances the application crashs with such a stack trace:

You aren't using the same CGContext from several threads, are you? That's unsupported. You have to create a new CGContext (or NSGraphicsContext) for every thread you draw from.

If that's not what you're doing, I have no idea, but statistics says it's probably something similar, that you're using something from two threads you shouldn't, or releasing an object in one thread that's still used in another.
