Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-9-generic x86_64
Distribution: Ubuntu karmic (development branch)

What I was doing when the application crashed:
As 196416 describes, selecting text then middle-clicking on desktop brings up a menu to select "Notes" or "Browser" (wording might not be exact). Selecting Notes crashes plasma.

 -- Backtrace:
