XOrg debug backtrace for skype crash.

This looks too much like bug 71415 or at least the behaviour is similar: When
using skype under OpenSuSE 13.1 with the XOrg Intel driver v 2.99.906 and the
default SNA accel method enabled the server crashes and returns to GDM login,
however the backtrace seems different from the one crashing empathy which I
reported back in bug 71415.

As a work around, and as you would suppose, switching back to older UXA fixes
this issue.

I'm attaching the trace. Let me know if you need more info. Thanks!
