Xorg GDB output

Crash happens when using empathy chat application on OpenSuSE 13.1 RC2. Filled
a bug in novell's bugzilla too but I thought that, after the backtrace I've got
from GDB, I should report this upstream.

I can reproduce this issue in two environments:

 - A thinkpad laptop with an Intel 3000 video chip
 - An acer aspire laptop with an Intel 4000 video chip

Steps to reproduce:

 1. Open empathy
 2. Scroll in any chat window that has the scroll decoration and some messages
 3. Xorg crashes and get's me back to GDM

Both machines have different chipsets I think (one sandy, one ivy) so I'm
guessing it does not have anything to do with the BIOS as Stefan on novell's
bugzilla sugested, plus there were no BIOS updates, at least for the Aspire,
available.

That being said I tried to debug Xorg by SSH. I'm attaching both machines
dmesg, lspci specs with -vv, uname output and the GDB stacktrace I could get
wich is the same for both machines. I lacked some debuginfo symbols installed
or that's what GDB told me, if you need anymore info please let me know.
