For this one, I'm not sure, but perhaps Alex's suggestions/code did help.

This is annoying enough that I've treated it as a bug. It's understandable
behavior, since unittest generates a SystemExit exception always, so ipython
is giving you that traceback. But there may be valid cases (such as this)
where you may want to quiet out any SystemExit raised. For that purpose, I've
added a new '-e' flag to %run:
-e: ignore sys.exit() calls or SystemExit exceptions in the script
being run. This is particularly useful if IPython is being used to
run unittests, which always exit with a sys.exit() call. In such
cases you are interested in the output of the test results, not in
seeing a traceback of the unittest module.
This will be part of the .14 bugfix release.
Thanks for the report,
