Nothing that's not in a Debian package.

However, now that you mention fonts...

I did have a problem with one font, 'Monospace', in that it was 'empty';
its letters were of zero width and, thus, non-readable. When using
X-Chat, I had to switch to a different font to see *anything* in the
chat window (the text would be printed by X-Chat, but due to the fact
that the font's letters were of zero width and non-printing, the chat
window was empty). This bug seems to have been fixed; and when I try to
reproduce the bug in Firefox now, I can no longer do so. I'm saying
'zero width', because when I typed something, my cursor wouldn't move,
while verifying the logs shows that X-Chat would think it was printed.

Since the 'Monospace' font is declared as one of Firefox' default fonts
(the one for monospace text, obviously...), I assume the two are
related. So, I think we can safely assume that the bug is in Firefox'
handling of fonts, where it assumes that font data is always
well-formed, and crashes if not.

Retitling appropriately.
