Description Jason Playne 2018-01-19 01:18:36 UTC 
Application: plasma-discover (5.11.0)

Qt Version: 5.9.3
Frameworks Version: 5.42.0
Operating System: Linux 4.13.0-26-generic x86_64
Distribution: KDE neon User Edition 5.11

-- Information about the crash:
- What I was doing when the application crashed:

I double clicked the "you have updated" tray icon.

I clicked update

It looked as if the tool did the "apt update" process and was about to start the apt upgrade process.

No dialog for "enter admin password" appeared before the crash

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

The backtrace looks mangled. Is there any way for you to reproduce?
If you are on neon, how come it's 5.11.0 instead of the last stable one?

There is a good chance this was an upgrade attempt from 5.11 to 5.12.

I have since been unable to reproduce :(

Each package upgrade since using discover has worked.

Thanks for the update; changing status.
