Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.1.38-50-pv x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
The first time it crashed was during normal operation, actually I was not using the computer at that moment, but now it crashes at every startup. 
Trying to find a workaroud, I moved all the files in the .config folder to a backup folder. I have reinstalled the Nvidia drivers several times in several versions, but plasma keeps crashing after reboot.

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