This sounds a bit like a problem that's fixed in Python 2.6 and will  
have a workaround in PyObjC 2.1.  In PyObjC 2.0 you'll get a hard  
crash in the following situation: a second thread calls one of the  
NSObject methods for executing a method on the main loop and there is  
an uncaught exception in that method.

If you use Python 2.6 (which is in alpha) the program will terminate  
unexpectedly instead (that is, the exception will stop the runloop on  
the main thread and your program will therefore terminate).

There's not much you can do about this, the cleanest way to avoid  
stopping your application is to add you're own method for executing  
code on the main loop and have that catch all exceptions. This can  
easily be build on top of the NSObject version.
