Description dusan.peterc 2016-03-08 16:59:52 UTC

Application: plasmashell (5.5.4)

Qt Version: 5.5.1
Operating System: Linux 4.1.15-8-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
A long standing bug (more than 4 years) in failed recognition of AltGr key (behaves as Enter after a couple of minutes after login; I need AltGR for national characthers) forces me to use a workarond:
Enter Kayboard layout from keyboard language switcher on taskbar, configure Keyboard, change switching policy from Global to Desktop and back, and AltGr works again.
But even this weird workarond stopped working, as simple keayboard configuration will take minutes to pop up, and crash plasma when it does.
No matter how much I try, it is becoming impossible to do any productive work on Plasma5.

The crash can be reproduced sometimes.

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