Version:            (using KDE 4.3.5)
OS:                Linux
Installed from:    Gentoo Packages

Each time when kontact started automatically with session startup, it crashes immediately. KWallet prompt shows, but kontact is already dead this time.
This happens only on one of my workstations, I can't reproduce it on others and I have no clue what is different.

When I start kontact second time, it works fine.

This was happening on kde-4.3.4, kde-4.3.5, qt-4.5.3, qt-4.6.1
dbus version is 1.2.3
dbus-glib version is 0.76
