Bug ID: 473668
Summary: Plasmashell crashes when trying to connect to OpenVPN
shortly after disconnecting
Classification: Plasma
Product: plasmashell
Version: 5.27.6
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: valdi...@gmail.com
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
Application: plasmashell (5.27.6)
Qt Version: 5.15.9
Frameworks Version: 5.108.0
Operating System: Linux 6.4.11-100.fc37.x86_64 x86_64
Windowing System: X11
Distribution: Fedora Linux 37 (KDE Plasma)
DrKonqi: 5.27.6 [KCrashBackend]
-- Information about the crash:
Plasmashell crashes (and automatically restarts) when the user disconnects from
VPN connection using NetworkManager plasma applet, and connects to the VPN
connection again (same or other) in about 1 second after disconnection.
This happens quite frequently, but not all the time. To prevent the crashes, it
is usually sufficient to wait 2 seconds before reconnecting to the VPN.
The bug is very old, I remember it happening for more than 3-4 years. KDE Crash
handler never cought it, for some reason it worked this time, that's why I
reporting it.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
