Comment 15 for bug 402017

This still happens under Lucid Beta 2, as well.

I should point out that (on my machine, at least) logging in and then logging back out, or rebooting the machine, or restarting X, results in the theme and colors returning to normal. It's not necessary to edit config files. That is, the unexpected theming is only temporary. Nevertheless, this is a weird usability bug, and disconcerting to a new user.
