Error in postscript creation

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 includes
this fix (as does svn).

It's been a couple of weeks, but I was finally able to chase down what I
think is causing the problem. I wasn't able to create a standalone script
that replicates the problem, as my application is very dependent on large
data sets, but I was able to create two versions of the postscript with
_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.
