Comment 20 for bug 274988

This bug seems to be pretty ancient; I'm guessing if it were still relevant we'd have seen more recent comments. In any case the backtraces have bitrotted; they no longer point into the right functions. So presumably code's been changed which has made this bug go away.

If I'm wrong and the bug can be reproduced on Karmic, feel free to reopen and attach a fresh Backtrace. A fresh Xorg.0.log couldn't hurt either.
