Sentry Crash Report:

Description dusan.peterc 2016-04-26 09:35:31 UTC 
Application: kdeinit5 (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.1.20-11-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
editing text in text editor.

AltGr key stops working, so I can't use national characters. I go in Keyboard configuration to change switching policy from global to desktop, and back, so that AltGr key starts working again. But on pressing OK, "Keyboard - KDE Control Module" crashes.
Before this happnes, the keyboard confiugration window takes a long time to pop up - 20 seconds to 2 minutes. This is a sure sign that it will crash when pressing OK on finished setting.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KDE Control Module (kdeinit5), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

Does it also crash if not using the NVIDIA proprietary drivers? If yes, it would be nice to have a valgrind backtrace. For more information, please see https://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_with_Valgrind
