Well, I'll be damned. I really can't believe this hasn't cropped up

The errant code is in matplotlib/backends/__init___.py
# Import the requested backend into a generic module object
backend_name = 'backend_'+backend.lower()
backend_mod = __import__('matplotlib.backends.'+backend_name,
Where the default backend is being imported. These changes were
introduced many moons ago by Fernando when he was cleaning up the
backend import for ipython/pylab. Then need top be moved to a
function or otherwise deferred until pylab asks for them, to prevent
the kind of problem you are seeing.

or change the default backend in the rc file to 'Agg'. Even though
there are 2 good workarounds, I still consider this to be a little bug,
because the OO interface shouldn't be doing any magic like importing a
backend implicitly. Would you be willing to file a bug report on the
