Bug ID: 372366
Summary: Plasma-Discover crashes every time I click on a
application after discover starts (e.g. on Firefox)
Product: kde
Version: unspecified
Platform: unspecified
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: blauerhun...@outlook.de
Target Milestone: ---
Application: plasma-discover (5.8.3)
Qt Version: 5.7.1
Frameworks Version: 5.27.0
Operating System: Linux 4.7.0-1-amd64 x86_64
Distribution: Debian GNU/Linux buildd-unstable (sid)
-- Information about the crash:
- What I was doing when the application crashed:
I started Discover out of the Kickoff-Launcher of Plasma 5.8. Once it's main
window appeared, I clicked on the first application in the list. Immediately
after that, drkonqi opens and tells me that a segfault happened.
The crash can be reproduced every time.
-- Backtrace:
Application: Entdecken (plasma-discover), signal: Segmentation fault
