Application that crashed: kontact
Version of the application: 4.3.0 pre
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2)) "release 138"
Qt Version: 4.5.1
Operating System: Linux 2.6.27.25-3-pae i686
Distribution: "openSUSE 11.1 (i586)"

What I was doing when the application crashed:
After the start up Kontact told me there is another instance of it running already. I clicked open new instance and ended up with 2 Kontacts running at the same time. I opened RSS feed reader in one. Checked some feeds, marked them as read and switched to mail view this then crashed Kontact.
