Hi, thanks for the bug report.
Just for sanities sake, did you have anything else using Glx active at this time? Compiz or anything like that?

[danda (dan-osc)]

Not that I'm aware of. I'm running kde at the moment, and compiz doesn't seem
to start under kde unless I start it manually. I did have Kaffeine open with
a movie (paused), but I think that just uses XV. Other open apps:
Konqueror, kmail, konsole, firefox.

I had this happen again this morning.

I haven't tested it yet, but I have a theory that it could be related to the screensaver. As both mornings when it occurred, I had left mythtv running overnight and the screensaver had activated.

I had this on exiting after watching a recording. Nothing else using GLX, only other user apps open were firefox and a terminal window (from where I'd launched MythTV -- it had hung on first run, so I'd "kill -HUP"'d it). I'm using fglrx.

Marking this as a duplicate of the newer bug because the newer bug has a stacktrace against trunk and is more likely to be fixed upstream
