After a substantial time away, I'm getting back into using cwm. One of 
the projects I'm working on reliably fails in the following manner, but 
I'm not sure if it's a bug with my data (if so, it seems like a pretty 
spectacular way to fail), or cwm. Does this look like a known problem 
in cwm? Perhaps something that's not friendly to Python 2.3 in the 
code?

This is the latest from CVS, with Python 2.3 (Apple's build) on OSX 
10.3.3.

Thanks,
