Application: kontact (4.4)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
During login, kontact is started twice and a dialog is presented saying that Kontact is already running and running a second instance could be dangerous. Clicking "No" closes both. Clicking "Yes" opens both, named "Kontact" and something like "Kontact <2>", each with an icon in the tray. Closing "Kontact" crashes kontact and closes both windows. Closing "Kontact <2>" first did not crash them until I closed "Kontact" (I only did this once).

According to pstree, all kontact instances are children of a single parent kontact process.

I'm using Arch Linux with kdemod.

This does not happen on my other accounts on this machine or on my machine at work also running up-to-date arch linux with kdemod.

The crash can be reproduced every time.
