Bug ID: 373865
Summary: plasmashell crashes on usb disconnect
Product: plasmashell
Version: 5.5.5
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: tho...@mitterfellner.at
CC: bhus...@gmail.com, plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.5.5)
Qt Version: 5.7.1
Frameworks Version: 5.29.0
Operating System: Linux 4.1.36-41-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"
-- Information about the crash:
I have a dual monitor setup where the external monitor is connected to the
laptop and has an usb hub to which mouse and keyboard are connected. When I
disconnect that hub from the laptop, sometimes I get this crash. The laptop
screen is turned off, if that matters; I'm writing this because I also had
other crashes in connection with the monitor (kwin crashed twice, also not 100%
reproducible) when I turned the monitor off (with gwenview in fullscreen mode).
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
