-- Information about the crash:
As explained at https://bugzilla.redhat.com/show_bug.cgi?id=2376531#c0, since I filed https://bugs.kde.org/show_bug.cgi?id=506642#c0, I've realised that closing "Quick Settings" too quickly after selecting "Apply", when I've selected a new global theme, causes the shell and application style to become inconsistent, which causes the shell to crash.

# Reproduction

1. Open "Quick Settings".

2. Select a new global theme.

3. Tentatively select "Apply" with your keyboard (as if you had hovered over it with your cursor).

4. Place your cursor over the window closure button.

5. Press "Enter" (or, maybe, the space bar), and really quickly afterward, close the window.

This shan't work 100% of the time.
