Comment # 18 on bug 859715 from Michal Kube��ek

Unfortunately I upgraded the machine where I encountered this issue to
Tumbleweed and apparently I forgot to backup the core dump. :-(

On Tumbleweed, suspend and resume are much more broken but when they succeed,
X server doesn't crash for another day (while on 13.1, it always crashed
within two hours after resume), I would say the issue has been fixed somewhere
in between.
