What backend are you using?  I have seen something like this on GTK*.
I'm pretty sure it is a threading problem.  Basically, we need a
backend dependent thread-safe way to make system calls.  Not a trivial
task.  I've posted a thread about this to the pygtk mailing list a few
months ago, but have yet to find a reliable recipe.  gtk gurus, please
advise.

In the meantime, you may want to try a different GUI backend, eg,
tkagg.  If this helps, let us know, because it will help determine
that this is indeed your problem.
