Version: 1.4.2 (using KDE 4.2.2)
Installed from: Ubuntu Packages
When I restart my system, Kontact tells me that it is already running (I didn't put it in any autostart, this happened by itself). When I answer here to start nevertheless, I have two kontacts running. Closing one of them causes both to crash.
Marking as duplicate of bug 187023. Thanks!
