Version:           unspecified (using KDE 1.2) 
OS:                Linux

I updated some KDE components via Yast last night. Before the update, everything was fine.
After the update, I wanted to check on my mail. I started up Kontact, and got a crash, the error report stating that Kontact was already running on another display (I have only one display) and that it should not be started.
After rebooting (cold and hot) still the same message. I then updated the whole KDE packages - and now I am getting the following output:

Details
Executable: kontact PID: 15868 Signal: 11 (Segmentation fault)

The Crash information reads as follows:

I have looked for the config file for this program, but can not find it, so I don't know whether something has changed.
Why is it that one updates one's software to a newer and supposedly better version only to have it crash on you? 
This happens on average with 85% of all updates - and I have learnt over the years to only update to stable versions.
At least, the crashes happen now on a stable periodic...
This is worse than windows, man!
