Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.1 (KDE 4.3.1) "release 165"
Qt Version: 4.5.2
Operating System: Linux 2.6.27.29-0.1-default x86_64
Distribution: "openSUSE 11.1 (x86_64)"

What I was doing when the application crashed:
KDE 4.3.1 completely crashed (received SIGSEGV error) immediately when I tried to remove a panel from the taskbar (a spacer if I recall).

I am using a relatively new install of OpenSUSE 11.1.
