Michael fixed a single quote bug in svn a while back. What version of
mpl are you using? The latest source release at
matplotlib - Browse Files at SourceForge.net includes
this fix (as does svn).

It's been a couple of weeks, but I was finally able to chase down what I

_almost_ identical input.

FYI, I know that single quotes in text strings do not _always_ cause an
error - this is easy to test with basic matplotlib text() calls. All I can
say is that _sometimes_ it causes problems.
