-- Information about the crash:
I wanted to switch from light to dark mode via the quick settings in the System
Settings app. After I tried to switch the apps turned into dark mode as
expected but the shell freezed and died directly with it. It didn't happened
again after that.

The crash does not seem to be reproducible.
