Qt Version: 4.8.6
Operating System: Linux 3.16.0-38-generic x86_64
Distribution: Linux Mint 17.2 Rafaela

-- Information about the crash:
- What I was doing when the application crashed: I tried to change the look of my digital date and time
Meanwhile the Browser was open (Mozilla Firefox) and I was copying file from my external HDD to my laptop.

The crash does not seem to be reproducible.

-- Backtrace:
Application: KDE beállítómodul (kcmshell4), signal: Segmentation fault
