Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-14-generic x86_64
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
I clicked on "add new widgets" on the top of the desktop.  Then I clicked on the download button for new widgets, the screen went blank, then crash.  KDE restored though so nothing was lost.  I think it was just a small internet timeout error or something, so i dont know what it was.  This isnt a recurring bug (  I think just a crash) so i dont know so ive given you the crash report so that you guys can inspect the bug and hopefully it will be patched.  Thanks for making KDE 4.3 such a good release its way better than my current GNOME desktop!
