Not sure if this is the right place, please redirect me if this is the wrong place to log this bug.

In my unittest I am testing a PyQt GUI app.  It brings up the app window, runs a few tests, then quit.  On quit I get a "Python quit unexpectedly while using the QtGui plugin" crash, below is a partial report from OS X:
