xterm output after plasma crash
Gentoo ~amd64. X server works fine and I can start it with "startx" from a
regular user. Then, I try to "startkde" from one of it's terminals. I see KDE
loading splash screen, but then it fades away and in terminal I see several
KCrash lines (attachment).
Then KDE crash reporter tool pops out, and here is info it provides:
Application: ksmserver (ksmserver), signal: Segmentation fault

Crash happens on a HP Envy dv7 laptop with hybrid graphics (intel+nvidia). I
have PC with pretty much the same software configuration (qt, kde versions and
compile flags) and everything just works.
Please tell me if you need any additional info about my system or about this
bug.
