This is the same problem I made a post about a few weeks back. It does occur
on Windows (at least for me) but only with the latest version of wxPython
(wxPython 2.4.1.2). It's in the bug trackers for Python (id 762198) and
wxWindows (id 746099) and has apparently been fixed but I don't know when it
will make it into a release.

If you run without signal handlers (reactor.run(installSignalHandlers=0)) it
doesn't occur.
