Bug 372366

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
