Hi Yuri,

A simple way to achieve this would be to create a comint output filter
function.  The `python-pdbtrack-comint-output-filter-function` is a nice
guide to start.  You would check with a regexp for the occurrence of an
exception and act accordingly.

I plan to add this to python.el.  If you'd like your implementation to
be considered feel free to propose it, otherwise expect my approach to
land in the next few weeks.
