This is not a matplotlib problem but an issue with Python itself. Unlike for example Tcl/Tk, Python does not have support for event loops. Each of the graphics backends (Tkinter, PyGTK, PyQT, the Mac OS X native backend) therefore each implement an event loop on their own. In general, these will clash with each other. Even IDLE's event loop (IDLE uses Tkinter) does not play nice with Tkinter itself: import Tkinter; Tkinter.Tk() opens a Tk window when run from the console, but does nothing when run from IDLE. Until Python itself supports event loops, I doubt that these problems will go away. I believe that ipython has made some progress in addressing these issues, but that of course won't help people who use regular python instead of ipython.
