I'm not sure what the problem is, but cutting and pasting the *actual*
traceback instead of retyping might help us find it, or at least would
help us trust everything you're saying.  Not having 100% confidence 
in a problem report (as in this case) tends to make one investigate
less intensely, I've found...
