I'm trying to debug an annoying bug in ksmserver that happens sometimes
leads to it's crash and logout process break. Main trouble that it
happens randomly, i can repeat 10 logouts in a row without issues, and
next one will be broken. One thing what i've noticed that crash happens
when some application didn't respond in time and buttons "Skip
notification" and "Cancel logout" appears in the shutdown process
window. I've also tested the logout with some SIGSTOP'ped apps and have
no issues.
That gives me a naive idea, that there have place some race condition
and when ksmserver is processing some "client" record, and in the same
time corresponding application is finishing it's work that leads to
deleting that "client" record, but i'm too newbie in the X transport and
other things so i may be wrong.
Here are 3 valid backtraces, due to reproducing instability i can't
collect more for this time. Maybe someone will have some idea about this
bug or methods to more stable reproduce?
