Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.1.21-14-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
Plasma chrashes every time I boot the system with the

openSuse Leap 42.1, Linux 4.1.21-14-default

GRUB option. Two identical bug reporting dialogs are opened, with slightly different timestamps.



If I select

openSuse Leap 42.1, Linux 4.1.20-11-default

GRUB option, system starts up normally.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted

If I press <Alt><F2>, krunner also crashes.

The only way of shutting down the system is <Ctrl><Alt><Del>, which also crashes kmserver, followed by short press on Power button on my box.

debug symbols would be needed for a better backtrace, in addition, bing an assert, also terminal output

Terminal output is impossible to get because of crash. Can't install debug symbols for the same reason. How do I boot to console?
Comment 5 samurai.unname 2016-06-17 01:08:46 UTC 
It all started when updating the proprietary NVIDIA driver after restarting and could not enter KDE was left with a black screen until you change the type of section could enter but did not appear like the desktop only yakuake nothing more
Comment 6 andrej.zupan 2016-06-23 09:34:05 UTC 
After upgrade to Linux 4.1.26-21-default, this bug no longer manifests itself. Looks like it's specific to version 4.1.21-14-default.

Marking as resolved.
