As always, post the *actual traceback*, not merely your interpretation of it.
Chances are you are stuck because you are overconfident that one part of 
your code works the way you think it does in all cases, when in fact it
does not.  Or maybe that's not the case, but nobody here will believe it
until you post the traceback and convince us. :)
