I wonder if you could extrapolate the line numbers of the backtrace if you had the stripped debugging symbols.

BTW, I think someone hosted debugging symbols for official packages, is it so?

Edit: this happened before libxxf86vm 1.1.4-1, dunno if that will change anything
After the xorg-server 1.17.1-3 update (with libunwind),
a nicer call-chain appears:

  • Field changed: Status (Assigned → Waiting on Response)
Please check with xf86-video-intel-2.99.917-4 in testing

I had it installed while it was still in testing, and
for probably more than 10 x sessions now no error appeared at exit.
It didn't happen every time before too, but I guess it's fine now.
