[Pyobjc-dev] Segmentation fault when patching a namespace

[Orestis M. <or...@or...>]

Hi,

as part of unit-testing our PyObjC app, I'm trying to use mocks for  
some Obj-C classes, to make things easier. Unfortunately it leads to a  
segmentation fault. Even more annoyingly I can't reproduce for a  
simple case.

Here's what the pattern looks like:

         from package import module as aModule
         original = aModule.CALayerSubclass

         milestoneModule.CALayerSubclass = Mock()

in 'module', we have, among others, the following:

	...more
	from Foundation import *
	from AppKit import *
	from Quartz import *

	from other.another import CALayerSubclass
	...more

and other.another has just these imports:

	import sys

	from math import ceil

	from AppKit import *
	from Foundation import *
	from Quartz import *


A similar situation, when extracted to three python modules and run  
works fine, so it's probably an interaction somewhere else.

Any pointers to what I should be looking at are welcome! I tried  
fiddling with sys.modules, in the suspicion that something somewhere  
is keeping a reference to the original class, but to no avail.


Thanks,
Orestis
