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:
- What I was doing when the application crashed:

Installing the recommended update using Discover. This happens everytime I update, regardless whether or not I have recently rebooted. In this particular case, my box has been up for 3 days without restart.

The crash can be reproduced every time.

-- Backtrace:
Application: Discover (plasma-discover), signal: Segmentation fault
