Threading module bug?

[Nadav Horesh]

I have problem with "pydoc -g" and MayaVi applications crashing with 
segmentation fault.
System: RH 8.0, gcc  3.2.1, python 2.2.2

Tracing the pydoc.cli() function I reached threading.py to the class 
"Condition" which raise the exception AttributeError on every asignment 
statment (for example in lines 152 and 160). All these exeptions
are intentionaly ignored with:

 except AttributeError:
     pass

but eventually the python machine halts with segmentation fault shortly 
afterward.

Any ideas?
