Bug ID: 416908
Summary: Plasmashell crash after clicking twice on ethernet
connection while connecting
Product: plasmashell
Version: 5.17.90
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: generic-crash
Assignee: plasma-b...@kde.org
Reporter: herzensch...@gmail.com
Target Milestone: 1.0
Application: plasmashell (5.17.90)
Qt Version: 5.12.5
Frameworks Version: 5.66.0
Operating System: Linux 5.4.0-12-generic x86_64
Windowing system: X11
Distribution: Ubuntu Focal Fossa (development branch)
-- Information about the crash:
I was having trouble connecting to my ethernet connection. The cable was in but
it wasn't connecting.
I clicked the Network widget (plasma-nm?), clicked once on the name of the
ethernet connection, clicked once again to see if the Details pane would appear
since I assumed the pane also appears when trying to reconnect.
Plasmashell then crashed. I verified that this was reproducible every time as
long as the ethernet was trying to connect.
Since this was my work machine, I tried to remove the ethernet cable and put it
back to restore connection, it didn't work.
Then I tried deleting the ethernet connection, remove the ethernet cable and
put it back, and the network was restored.
After it was restored, the crash was no longer reproducible.
In other words, under the correct conditions, the crash can be reproduced every
time. With proper internet connection it cannot.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
