Bug 417674

Application: systemsettings5 (5.17.5)

Qt Version: 5.13.2
Frameworks Version: 5.66.0
Operating System: Linux 5.4.14-200.fc31.x86_64 x86_64
Distribution: "Fedora release 31 (Thirty One)"

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

I typed Alt+F2, typed "systemsettings" and pressed Enter.  To my surprise, Rhythmbox launched.  I closed it.

Once again, I typed Alt+F2, typed "systemsettings" and pressed Enter.  System Settings seems to have started, but immediately crashed.

- Unusual behavior I noticed:

I didn't expect Rhythmbox to start.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
