Description Dominik Stańczak 2019-01-03 11:02:17 UTC
Application: plasmashell (5.14.4)

Qt Version: 5.12.0
Frameworks Version: 5.53.0
Operating System: Linux 4.20.0-arch1-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
I was changing my wallpaper from Folder View with a large (7.2Mb) wallpaper to one of the default Image ones. This was on my second screen, plugged in via HDMI to my nvidia card with intel-virtual-output. When I switched from "Slideshow" to "Image", the plasma shell crashed and restarted after a few seconds. This did not occur as I tried again, but I've had this crash before, so it's not a one-off thing.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault

Unexpectedly, I don't even have a plugins directory! lib64 is there, though.

05:50:38 dominik: ~ $ ls /usr/lib64/plugins/kf5/kirigami
ls: cannot access '/usr/lib64/plugins/kf5/kirigami': No such file or directory
05:51:42 dominik: ~ $ ls /usr/lib64/plugins
ls: cannot access '/usr/lib64/plugins': No such file or directory
Comment 4 Kai Uwe Broulik 2019-01-22 08:22:15 UTC
Perhaps /usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kirigami/ or /usr/lib64/qt5/plugins/kf5/kirigami, something along the lines
