Sounds like an instance of the borrowed reference problem[*], but then 
I would expect it to happen with 2.3b2 too...

[*] there are a number of Cocoa routines that keep a reference to an 
object you pass in, but without doing the retain(). For ObjC programs 
this tends to be harmless, but not for PyObjC programs. A quick check 
to see whether this is the problem is to keep a reference to the Python 
object, that will work around this problem.
