Here's a clue: please always cut and paste the *entire actual* traceback 
when you report a Python error.

If it's not a Python traceback, spend the time to retype -- carefully -- 
the exact text from the dialog where the error was reported.  If it's 
one of those awful Windows crash dialogs with reams of useless 
information, spend some time thinking about what portion of that would 
be most likely to be of help to us, if you can't retype all of it.

Also consider reporting on version numbers of things: Python, 
Pyparallel, WinXP (SP2 for example?), just in case that matters.
