Qt Version: 4.8.2
Operating System: Linux 3.6.2-4.fc17.x86_64 x86_64
Distribution: "Fedora release 17 (Beefy Miracle)"

-- Information about the crash:
After resuming from suspend to RAM where I was previously running with just a laptop monitor and now connected to a docking station with an external monitor attached, I was presented with the Systems Settings dialog for configuring monitors.  After selecting to enable the second display and hitting OK, this crash was produced.

-- Backtrace:
Application: KDE Daemon (kded4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
