Attached a patch to display warning when user calls show() with non-GUI backend. This addresses Joerg's difficulty -- that it's hard to know what's wrong when matplotlib is mis-configured to not show a window.
This patch can be considered optional. The real bug here is that matplotlib is misconfigured to use a non-GUI backend as the default.
