Bug ID: 393979
Summary: discover crash upon visiting settings
Product: Discover
Version: 5.12.4
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: normal
Priority: NOR
Component: discover
Assignee: aleix...@kde.org
Reporter: mohammed_elaf...@yahoo.com
Target Milestone: ---
Application: plasma-discover (5.12.4)
Qt Version: 5.10.1
Frameworks Version: 5.44.0
Operating System: Linux 4.16.5-300.fc28.x86_64 x86_64
Distribution (Platform): Fedora RPMs
-- Information about the crash:
- What I was doing when the application crashed:
I was trying to view the discover app settings. Once I clicked the settings,
the application crashed.
- Custom settings of the application:
The rpmfusion-nonfree repository is configured and enabled.
I should add that the problem seems deeper than being related to discover
alone. Upon trying to run the following command from the shell
sudo pkcon refresh force
I always get the following error at the end:
Fatal error: Error when getting information for file
“/var/cache/PackageKit/28/metadata/rpmfusion-nonfree/repodata/appstream.xml.gz”:
No such file or directory
At one time one I issue the `pkcon refresh' command it didn't spit out the
error message. Consequently discover app didn't crash ever since.
The crash can be reproduced every time.
-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
