Sentry Crash Report:

Description Daniel Tang 2020-04-25 05:02:22 UTC 
Application: systemsettings5 (5.18.4)

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.4.0-26-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04 LTS

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

1. Make sure that Breeze Dark is the current global theme
2. Open System Settings
3. Open and switch between some random modules (I don't remember which)
4. Open the global theme module
5. Select "Breeze"
6. Click "Apply"
7. Notice that the system becomes a mix of both themes for a moment
8. Notice that the System Settings window disappears
9: Notice that the system is now in the Breeze theme

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
