Bug ID: 391245
Summary: Systemsettings often crashes after browsing and then
attempting a search
Product: systemsettings
Version: 5.12.2
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-bugs@kde.org
Reporter: ystein@posteo.net
Target Milestone: ---
Application: systemsettings5 (5.12.2)
Qt Version: 5.10.0
Frameworks Version: 5.43.0
Operating System: Linux 4.4.0-116-generic x86_64
Distribution: KDE neon User Edition 5.12
-- Information about the crash:
- What I was doing when the application crashed:
See Screencast.
- Opened System Settings.
- Browsed through categories randomly and quite quickly.
- Then I typed something random into the search field. At this point
systemsettings crashes sometimes.
- Then I browsed randomly again.
- Then I typed into the search field again. At this point systemsettings
crashes most times.
- Unusual behavior I noticed:
I had just switched my locale into Suomi and restarted the session.
I also have an ext. HDD attached.
I don't know if these are causes, just noting them here in case.
System:
- Neon 5.12.2
- Kernel 4.4.0-116
- Frameworks 5.43
- Qt 5.10.0
I am attaching a nice backtrace after installing the necessary dbgsymbols. The
Bug Report Wizard awarded me three stars! I'm proud.
The crash does not seem to be reproducible.
-- Backtrace:
Application: Järjestelmäasetukset (systemsettings5), signal: Segmentation fault
