Application: plasma-discover (5.10.5)

Qt Version: 5.9.1
Frameworks Version: 5.38.0
Operating System: Linux 4.13.0-43-generic x86_64
Distribution: Ubuntu 17.10

-- Information about the crash:
- What I was doing when the application crashed:
Opening discover updates from system tray

BTW It is really hard to submit a crash report. I m writing these to satisfy min report length

The crash can be reproduced every time.

-- Backtrace:
Application: Discover (plasma-discover), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
