That's a good one ;) There are some pretty clever things done with threading when you do "ipython -pylab" to make the GUI and the shell responsive at the same time. I wonder if you've entered a race condition/deadlock or something. A useful piece of information is whether you are running on a multi-core machine. Have you ever seen it lock up if you don't use "-pylab"? (In that case it would be normal for the shell to stop responding, but the GUI should still repaint and resize etc.)
There may be others on this list who are of more help than me, but you may also want to ask your question on the ipython mailing list if we can't solve it here. I suspect this is related to the interaction of the two projects.
