About every second or third time I try to start kontact, it doesn't fully start. It doesn't open its window and a process /usr/bin/kontact is sitting around and waiting for something (see below). When I pkill kontact and try again it usually comes up.

19505 appears to be some thread. 19491 is kontact.

I am sending this now, as this time Kontact crashed after the pkill kontact and starting it again habit of working around that issue. I started Kontact on the konsole cause I wanted to try several cycles to have it hang again, maybe it says something to the console. I will report the second crash via DrKonqi before adding more info to this one.
