Application that crashed: kontact
Version of the application: 4.3.1
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.31.1 i686

What I was doing when the application crashed:
Sometimes when I start KDE and Kontact loads (from a saved session) and I am not connected to a network, it shows a bunch of errors about how it can not connect to any of the hosts, and after I click OK on all of them, it crashes. This happens about once every other time.
