Bug ID: 414116
Summary: Plasmashell aborted when its Wayland connection broke
Product: plasmashell
Version: 5.16.5
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: matthew.fagn...@utoronto.ca
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.16.5)
Qt Version: 5.12.5
Frameworks Version: 5.64.0
Operating System: Linux 5.3.11-300.fc31.x86_64 x86_64
Distribution (Platform): Fedora RPMs
-- Information about the crash:
- What I was doing when the application crashed:
I updated from KF 5.61 to 5.64 in Plasma 5.16.5 on Wayland in Fedora 31. I
logged out of Plasma. I logged into Plasma on Wayland from sddm. I noticed that
the Task Manager and NetworkManager applet were semi-transparent. I opened
System Settings. I typed transparent in the search bar and selected Desktop
Behavior. I typed transparent in the search bar. I clicked on the box with the
two arrows beside Blur. I disconnected from Wifi and connected to Ethernet
using the NetworkManager applet. The System Settings window showed Not
Responding in the title bar. plasmashell aborted with an error message that the
Wayland connection had broken "The Wayland connection broke. Did the Wayland
compositor die?". System Settings aborted with the same message.
- Unusual behavior I noticed:
The Task Manager disappeared. The background went black. plasmashell restarted
automatically.
-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
