Bug ID: 396346
Summary: Discover crashes upon launch
Product: Discover
Version: 5.13.2
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: discover
Assignee: aleix...@kde.org
Reporter: yst...@posteo.net
Target Milestone: ---
Application: plasma-discover (5.13.2)
Qt Version: 5.11.0
Frameworks Version: 5.47.0
Operating System: Linux 4.15.0-24-generic x86_64
Distribution: KDE neon User Edition 5.13
-- Information about the crash:
- What I was doing when the application crashed:
Launched Discover after changing the system colour scheme. Had also recently
removed a global menu, but unsure if it's related.
I triggered the crash two times. The second was a freeze – attaching gdb
backtrace in next comment .
The crash can be reproduced sometimes.
-- Backtrace:
Application: Oppdag (plasma-discover), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
