Having the traceback follow the error message makes it difficult for the
user to find the error message, so it really should exit gracefully
instead of crashing.  

I would say that a program crashing is a bug, even if it's at the moment
a low priority bug because of not being a regression.

Because the error that causes the crash in this case is properly
detected, fixing the crash is probably pretty easy.

Of course you cannot really play a fugue in three continuous parts on
the violin, but by dint of doublestopping and dodging from one part to
another, you can evoke a hideous ghost of a fugue that will pass
current if guaranteed by Bach and Joachim.
