It seems this bug was introduced with the mesa 7.4 update: libgl1-mesa-
glx (7.4-0ubuntu1). Downgrading this package to the previous
7.3-1ubuntu4 version solved the problem for me.
(I grabbed the old version of the package from here:
https://launchpad.net/ubuntu/jaunty/amd64/libgl1-mesa-glx/7.3-1
FYI, I see this mythfrontend crash as well, since upgrading packages a
couple days ago.
