Bug ID: 387089
Summary: Discover and other crashes.
Product: Discover
Version: 5.8.8
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: discover
Assignee: aleix...@kde.org
Reporter: itt...@hotmail.com
Target Milestone: ---
Application: plasma-discover (5.8.8)
Qt Version: 5.6.1
Frameworks Version: 5.36.0
Operating System: Linux 4.4.0-101-generic x86_64
Distribution: Ubuntu 16.04.3 LTS
-- Information about the crash:
- What I was doing when the application crashed:
nothing, the only thing running this last time was Discover. other times I had
firefox running. Aport (and sometimes other crash notices) also seems to crash
often after Discover crashes during/after update (meaning the download bar(s)
never seem to complete, then it crashes; though it doesn't prompt for those
updates again. I would like to upgrade from 16.04 but Discover does never
shows any upgrades. I did like the functionality of Mulan before Discover.
The crash can be reproduced every time.
-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
