Bug ID: 381188
Summary: Discover crash on start
Product: Discover
Version: 5.10.1
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: discover
Assignee: aleix...@kde.org
Reporter: mustafa10...@gmail.com
Target Milestone: ---
Application: plasma-discover (5.10.1)
Qt Version: 5.7.1
Frameworks Version: 5.35.0
Operating System: Linux 4.11.0-2.fc26.x86_64 x86_64
Distribution (Platform): Fedora RPMs
-- Information about the crash:
- What I was doing when the application crashed:
Just opened discover on a fresh installation of F26 beta, happens everytime.
I think I know the problem, flatpack is not installed, maybe this is causing
the crash.
I didn't generate better backtrace because I think I knew the problem, I can do
so if you want, but after installing flatpak it doesn't crash on start anymore.
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".
