Can you provide the smallest test script that reproduces this error?  Also, if 
there are multiple functions being called, it would be great to know where in 
the script it fails.

It looks like there is a bug in a Python __del__ implementation, possibly 
corrupting memory?  I'd like to focus my search on the most likely objects 
going out of scope.

Thanks.

Also, can you retest with 2.1.8 or the latest from git.  There were fixes that 
could explain this.

the latest 2.1.8 works now.  I am using ubuntu 10.10 and python 2.6.6.
