Description svebran 2017-10-12 16:57:18 UTC

Application: plasmashell (5.11.0)

Qt Version: 5.9.2
Frameworks Version: 5.38.0
Operating System: Linux 4.9.54-1-lts x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
Crashes happen by pressing on 'Add Widgets' button and when trying to move or delete or even use existing widgets. I Use KMS drivers and variables areset accordingly:
GDK_BACKEND=x11 (when i choose wayland, all the programs which use GTK won't start because of unability to find screen)
QT_QPA_PLATFORM=wayland-egl
CLUTTER_BACKEND=wayland
SDL_VIDEODRIVER=wayland

The crash can be reproduced every time.

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