Well, there's a difference between it crashing (bad description in Python --
it's really an unhandled exception) and it printing an error message.  You
seem to mean the former -- but in any case, it's a bug in TMDA, as it should
handle all the exceptions that can occur.

But it didn't do this.

Yes.

You should report this to the TMDA list or author.

I can tell you why, now, having seen the above:  TMDA has a default exception
handler that actually prints the above (you can manually print a traceback in
Python) -- getmail has one, too.  However, TMDA should exit nonzero if it does
this.  If it exits zero, there's no way for the invoking program to know
something went wrong.
