Chris,
I suspect it is a problem with your matplotlibrc file; you could try
stripping it down to bare minimum, as in the svn root directory.
Another possibility is that your update is somehow incomplete or
scrambled with an earlier installation.
If that doesn't work, try making a minimal script that illustrates the
problem.
examples/newscalarformatter_demo.py works fine, so I don't think the
basic subplot mechanism is broken.

I think this is a valid key in rcParams.
Doesn't the error trigger a full traceback that shows where it is coming
from?
I am still getting this problem. Here is an ipython traceback of a very
simple plot:
In [1]: from pylab import *
In [2]: plot([3,45,6],[7,9,2])

The thing is, I deleted my entire ~/.matplotlib directory, hoping to start
clean. Where does matplotlib get its info when a .matplotlibrc is not
present in my home directory?
