If I may quote from the matplotlibrc file:
#text.latex.preamble :
# IMPROPER USE OF THIS FEATURE WILL LEAD TO LATEX FAILURES
# AND IS THEREFORE UNSUPPORTED. PLEASE DO NOT ASK FOR HELP
# IF THIS FEATURE DOES NOT DO WHAT YOU EXPECT IT TO.

It looks like the text line is a problem. Latex doesnt like use of align or
eqnarray environments inside figures. It looks like a latex limitation, not
matplotlib. On the other hand, if you can figure out how to make it work in
latex, and can prove that it is a limitation in matplotlib, please let me
know so we can fix it.
