Group,
This error occurs for me with Matplotlib 0.99.1, Python 2.5.4 and 2.6.2, while
using the Qt4Agg backend on Windows XP.
Basically, savefig('aweomse_plot.pdf') barfs if I have some math text in there.
For example:

Spits out a nasty error at Input Line 7. I've include it below my sig for those
who might want to look at it.
I don't know much about back ends, but I feel like I've neglected to install
something since the last line of the TraceBack includes "ValueError: unichr()
arg not in range(0x10000) (narrow Python build)".
I have an update-version of MikTeX on this machine. Any thoughts?
Many thanks,
