Bug#599329: Somewhat useful backtrace

Tue Mar 29 19:42:55 UTC 2011

Package: libva-x11-1
Version: 1.0.8-3
Severity: normal

I rebuilt vdpau-video-0.7.2 with noopt,nostrip to get a more useful
backtrace. It ignored noopt, but did manage to not strip.

Will try and fix that problem and followup again.
