When running in Wing's debugger, we stop the Python interpreter
completely while stepping or at breakpoints, so the debug process
event loop isn't serviced and its windows will not update. We're going to
look into adding hooks for forcing updating during debugging fairly soon,
since this has become a commonly reported problem.

Can you confirm whether this crash happens only in our debugger or
also when run outside of Wing?
