Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.32-ARCH x86_64

What I was doing when the application crashed:
I had tried moving the Notes plasmoid onto a panel to see if it would be usable there.  It wasn't.  I moved it back to the desktop, and began updating some text in the note.  After playing around with it for a bit, the entire plasma workspace crashed.
