I've been looking at this, but haven't made much progress. Try this with
backend:gtkcairo in matplotlibrc:
$ python
>>> __import__('matplotlib.backends.backend_ps', globals(),\
locals(),['backend_ps'])
output:
<module 'matplotlib.backends.backend_ps'
from '/usr/lib64/python2.4/site-packages/matplotlib/backends/backend_ps.pyc'>
$ ipython
In [1]: __import__('matplotlib.backends.backend_ps', globals(),\
locals(),['backend_ps'])
output:

If you change backend:gtkagg in matplotlibrc, then ipython doesnt complain.
Very strange.
