Bug 216081

Application that crashed: konqueror
Version of the application: 4.3.3 (KDE 4.3.3)
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.3
Operating System: Linux 2.6.31-ARCH i686

What I was doing when the application crashed:
I opened a folder in a new tab in konqueror and it crashed. for some seconds (4 at least) the plasma panel dissapeared and after reappeared. Kwin also crashed (I will report that by opening another bug report. I will put the url in a comment here).
