Re-using pyglet.Text.Label appears to leak memory

What steps will reproduce the problem?
1. Running the attached file, on Python 2.5. Eventually some of the text
appears to be rendered wrongly (out of video memory?) and the process's
working memory set continues to rise.

Output of tools/gl_info.py:

I'm afraid I'm not going to go to the trouble of installing an SVN client just 
to
test a bug, sorry. If you think it's been fixed since the beta, then fair 
enough. You
can have the output of 'python -m pyglet.info' if it's any use, though.
