[Python-Dev] Re: Fatal Python error: GC object already in linked list

[Steve Alexander]

Thanks Guido.

I have the problem reproducable at will now, although I haven't narrowed 
it down to something reasonable to package up as a test case. (It 
involves many parts of Zope 3.)

I have no idea how to go about looking into this further, but I'm 
willing to try any reasonable suggestions to see where things are 
tripping up.
