Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.1 (KDE 4.3.1) "release 179"
Qt Version: 4.5.3
Operating System: Linux 2.6.27.29-0.1-trace i686
Distribution: "openSUSE 11.1 (i586)"

What I was doing when the application crashed:
While downloading a pdf in firefox the crash occured.
Think this is related selecting/clicking to the notifications pop-up or icon.
