Bug ID: 408510
Summary: KDE Plasma crashes when unlocking it after system
suspend
Product: plasmashell
Version: 5.14.5
Platform: Debian stable
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: j.andra...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.14.5)
Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 4.19.0-5-amd64 x86_64
Distribution: Debian GNU/Linux 10 (buster)
-- Information about the crash:
Often, but not always, after I resume from suspending the system, Plasma
crashes after I introduce my password to unlock the screen. When this happens,
I get an "xmessage" window with the following error: "Could not start
ksmserver. Check your installation.", and Plasma reloads.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
