Git commit 370e5776b70a98efa2abd42452f78748cc5f25db by Alexander Lohnau.
Committed on 30/11/2020 at 12:53.
Pushed by alex into branch 'master'.

Reuse QWidgets dialog

Otherwise the engine would make a new network request, this is quite
wasteful and lets the user wait a moment.
Also this appears to fixes the crash, you can try this out by quickly
opening and closing the dialog.

Additionally this makes it consistent with the QtQuick one.

>From the stacktrace I got this seems to fix BUG 429302.

Sometimes I can reproduce with these steps:

1. open system settings > window management > task switcher
2. click on "Get new task switchers..." button
3. close "Get new task switchers..." window while "Initializing" message appears
4. click on "Kwin scripts" KCM
5. click on "Get new scripts..." button
6. close "Get new scripts..." window  while "Loading more..." message appears

I can consistently reproduce with these steps, even with a clean .cache folder.
The backtrace from comment #c13 points to a different issue though.

This one can't be reproduced anymore on my end.

Also,  #13 shows a different issue, kwin ralated if i am not mistaken.

I also can not reproduce on neon unstable.

Operating System: KDE neon Unstable Edition
KDE Plasma Version: 5.22.80
KDE Frameworks Version: 5.85.0
Qt Version: 5.15.3
Graphics Platform: X11

Phew!
