My guess is that this has nothing to do with partitions and that you
may be reading two different rc files. One has

  backend : WxAgg

which is erroneous (should be WXAgg)

and the other has the win32 default

  backend : TkAgg

which is working for you.

To test, create a script test.py

  import pylab

and run it on both partitions with

  python test.py --verbose-helpful

This will tell you which rc file is being loaded, what backend is
chosen, etc.

Don't I feel silly. --verbose-helpful is quite helpful. I was loading an rc file I didn't know I had saved in the directory where another test script was saved. I deleted that other rc file with the bad backend string and everything is fine.
