Version:            (using KDE 4.1.3)
OS:                FreeBSD
Installed from:    FreeBSD Ports

I'm running PC-BSD 7.0.2, right out of the box. I started the "system settings" application, and selected the "system settings" icon, clicked the "tasks" tab, and finally clicked "fetch ports".

It runs for maybe 10 seconds and then says:
A Fatal Error Occurred
The application KDE Control Module (kcmshell4) crashed and caused the signal 11 (SIGSEGV).
Please help us improve the software you use by filing a report at http://bugs.kde.org. Useful details include how to reproduce the error, documents that were loaded, etc.

Here are the details it gave me:
