vainfo does not crash on another system with an "Ivybride" GPU.

[Sebastian Ramacher (s-ramacher)]

Please install i965-va-driver-dbg and provide a backtrace for the crash. If the crash happens somewhere in i965_drv_video.so, the bug should be reassigned to the correct package.

[Laurent Bonnaud (laurent-bonnaud)]

I installed many relevant *-dbgsym packages instead and got a backtrace. Unfortunately I could not get apport to upload it to launchpad. So here it is:

I updated the BIOS of my Ivybride system and now vainfo also crashes on this system.

[Laurent Bonnaud (laurent-bonnaud)]

I finally got apport to report the bug properly to launchpad so I created a new bug and I will merge this one...
