New submission from Peter Hansen <pe...@engcorp.com>:
In platform.mac_ver() there is a call to look up Mac version info, which
results in a call to gestalt.gestalt('sysu'). This call is useless since, as
documented in comments in the function the "sysu" option no longer exists, but
the call was left in "as documentation".
Unfortunately, as described in
http://groups.google.com/group/wxpython-users/browse_thread/thread/ced6c57cc84cb252
this call has the unfortunate and mysterious (but conclusively proven) side
effect of preventing a wxPython app from running the GUI main loop in any
thread other than the main thread (or rather, the one in which this failing
call to gestalt() is first made).
See also http://bugs.python.org/issue780461 for some related background.
