Comment # 3 on bug 931309 from Maxim Marinchenko

Sorry for late response...

Yes, I was able to reproduce the crash soon after log into KDE 4 desktop
(sometimes but not always). I attached short Xorg.log for clearness.

This bug seems to be related to Intel SNA. I was able to workaround the problem
by switching driver to legacy Intel UXA mode. And it is fixed now, I guess. At
least I cannot reproduce the crash after applying the following patch:

federico@suse.com
- U_sna-glyph-null-deref.patch
  Fix crash on PRIME setups when executing empty glyph strings (bnc#906972)

Thank you for your support!
