Description Michael Sparks 2018-10-10 21:35:00 UTC 
Application: plasma-discover (5.12.6)

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-36-generic x86_64
Distribution: Ubuntu 18.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I saw that the "Updates" widget on my notification area had a blue dot.  I clicked it to launch Discover so that I could apply the updates.  The Discover window displayed briefly (about 2 seconds) in an incomplete state, and then went away.  A crash handler popped up just before the Discover window disappeared.

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".
