Application: systemsettings5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-32-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
I was in the main menu of system settings, switching to window appearance and directly to window border, after few seconds (1-10) systemsettings crashes. Even if I come from an other tab of the window appearance menu, when I switch to window border it crashes.
I recently installed a window border theme I don't remember, but I can't have its name because I can't use this menu

The crash can be reproduced every time.

-- Backtrace:
Application: Configuration du système (systemsettings5), signal: Segmentation fault
