Bug 348849

Application: kdeinit5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-18-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- I installed Evanos window decoration
- I did not find it good, so i wanted to switch back to default
- I right-clicked on the titlebar of the terminal and tried to change it that way.
- The Settings opened, and even before i could click on it, it crashed. (segmentation fault: 11)
I was able repeat this, but after disabling that Evanos (It worked via the Settings Program) it worked again.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE-Kontrollmodul (kdeinit5), signal: Segmentation fault
