I think Tijs is right. raise (with no arguments) will raise the *last*  
exception, not the one that was active when you entered the except clause;  
it preserves the traceback.
Either replace the inner try/except using getattr, or save the full  
exception details (including traceback) and use the 3-argument form of the  
raise statement.
See http://docs.python.org/ref/raise.html
