Application: plasma-discover (5.13.5)

Qt Version: 5.11.1
Frameworks Version: 5.50.0
Operating System: Linux 4.18.0-10-generic x86_64
Distribution: Ubuntu 18.10

-- Information about the crash:
- What I was doing when the application crashed:
Attempting to configure permissions on a running application

Steps to reproduce:
1. Open Discover
2. Search "temperature"
3. Select "Hardware Sensors Indicator" (application is currently installed, and running)
4. Click "Configure Permissions"
5. Check box for udisks2

Result: Discover instantly crashes


- Custom settings of the application:
Under settings, I have 4 headings: Flatpak, Snap, Ubuntu (default), and Missing Backends. The only heading with anything under it is Ubuntu (default), and in there, the non-source version of each Cosmic pair is checked.

Configured sources:
Ubuntu software: main, universe, restricted, multiverse
Other software: Canonical Partners, http://ppa.launchpad.net/oibaf/graphics-drivers/ubuntu


- Additional information:
I reviewed bug 397585, and determined that this is not a duplicate of that bug, because although that bug was reported in version 5.13.4 and marked fixed, I am running a newer version of Discover.

The crash can be reproduced every time.

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