Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-15-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I accidently opened an empty text document twice with kate, then I wrote some stuff to it in one window, and when I closed this one (the other was still open) and said "dont save", Plasma crashed

 -- Backtrace:
