Bug 221326

Application that crashed: systemsettings
Version of the application: 1.0
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.9-174.fc12.i686 i686

What I was doing when the application crashed:
I was using digiKam, and I decided to use the Facebook downloader plugin.  To use it, I had to authenticate with the facebook website.  The crash occurred when konqueror had to open to display the facebook login page.

 -- Backtrace:
Application: System Settings (systemsettings), signal: Segmentation fault
