[Zope-dev] Zope process killed

[Roché Compaan]

When I try to view or delete a particular folder the Zope process (on
Zope 2.4.3) suddenly gets killed with this message in the log:

python2.1: Python/ceval.c:695: eval_code2: Assertion `(stack_pointer -
f->f_valuestack) <= f->f_stacksize' failed.

I climbed into the python debugger and found the place where this
happens.  The culprit is a particular python script inside this folder
and as soon as the the setstate method is called on this script this
happens.  The exact place is in the "_newfun" function in
PythonScripts.py on line 315: exec code in g, l.

here is the ouput of locals() if this might help:

Any help will be much appreciated.
