Bug ID: 390001
Summary: Systemsettings segfault when quitting from plasma-nm
settings panel
Product: systemsettings
Version: 5.11.5
Platform: Archlinux Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Application: systemsettings5 (5.11.5)
Qt Version: 5.10.0
Frameworks Version: 5.42.0
Operating System: Linux 4.9.73-1-lts x86_64
Distribution: "Arch Linux"
-- Information about the crash:
- What I was doing when the application crashed:
* Selected the plasma-nm connection settings panel under Network>Connections.
* Did NOT make or apply any changes
* Quit the Settings application using the Ctrl+Q shortcut.
* This is when the segfault happened.
- I can't reproduce the bug ad-hoc (i.e. by simply repeating the above sequence
of actions once or more).
- I seem to recall that a similar case has happened before.
The crash can be reproduced sometimes.
-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
