Oh, ok. Its python.

Partially. If I close the file, and then reopen it, I get my monospaced fonts 
back. I did not realize that you had such control over the fonts for the 
various lexers. So as it stands, I have DejaVu sans mono set for all of my 
editor/style(1) fonts, which seems to give me monospaced fonts when I open an 
existing python file, and I have these python-specific settings which only 
take effect when I save a new file as .py.

I think there is some conflicting configuration going on, but I think I can 
work around it. Thanks for pointing out the lexer-specific settings.
