Bug ID: 488709
Summary: Plasma crashed when connecting to a network with the
plasma-nm applet
Classification: Plasma
Product: plasmashell
Version: 5.20.5
Platform: Debian stable
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: santiagopi...@gmail.com
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
Application: plasmashell (5.20.5)
Qt Version: 5.15.2
Frameworks Version: 5.78.0
Operating System: Linux 5.10.0-22-686-pae i686
Windowing system: X11
Distribution: Debian GNU/Linux 11 (bullseye)
-- Information about the crash:
- What I was doing when the application crashed:
I opened KRunner to write a password there because the plasma-nm applet changes
the network selected to connect to while writing the password: if the network
list refreshes, the selected network is the one that happens to end in the same
position as the previously selected one. This happens consistently on this
version of KDE/Plasma, which is outdated and I don't know if the issue has been
corrected already, so I'm not reporting that issue.
The issue here happened when I selected the password in KRunner, copied it,
closed KRunner with the Escape key, then clicked on the plasma-nm tray icon,
selected the network I wanted to connect to, and quickly pasted the password in
the field with Ctrl+V and pressed Enter. The whole desktop flickered a bit and
DrKonqui informed me that Plasma crashed; the connection to the network didn't
succeed.
- Unusual behavior I noticed:
The problem with changing selected networks in plasma-nm applet.
I could connect to the network later with no problems. Also, I couldn't
reproduce the issue again by doing the same. One particular thing to note is
that I experience frequent disconnects from WiFi, possibly related to this
driver bug: https://bugzilla.kernel.org/show_bug.cgi?id=203709
I reviewed the other bug reports suggested as possible duplicates, both the
suggested ones and the ones originally reporting the same bug; while the stack
trace is very similar at the top and in the middle compared to those reports,
they are not exactly equal; also the context of the crashes are rather
different. As such, I am reporting this crash as a separate bug report since I
am not sure whether the suggested duplicates are really that.
PD: KDE is great, good work!
The crash does not seem to be reproducible.
