Bug ID: 386847
Summary: Discover chrashes after update
Product: Discover
Version: 5.8.8
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: discover
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Application: plasma-discover (5.8.8)
Qt Version: 5.6.1
Frameworks Version: 5.36.0
Operating System: Linux 4.4.0-98-generic x86_64
Distribution: Ubuntu 16.04.3 LTS
-- Information about the crash:
As of recently when prompted for a software update every time Discover crashes
after a software update process is completet. SW updates seem OK but finishing
Discover seems to be a problem.
Starting and closing Discover from the applications starter menu works without
problem.
The crash can be reproduced every time.
-- Backtrace:
Application: Entdecken (plasma-discover), signal: Segmentation fault
