Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.26.8.tex3 i686
Distribution: "PCLinuxOS"

What I was doing when the application crashed:
I had just exported my bookmarks from Opera to Desktop as an html list. I clicked to open it and check the integrity of the list. As soon as it opened plasma crashed. The crash handler popped up; I agreed to report this crash to you and restart the plasma desktop. It did restart promptly.
