Comment 7 Akseli Lahtinen 2023-11-28 08:34:09 UTC 
I am unable to reproduce this even after following the notes in https://bugs.kde.org/show_bug.cgi?id=477540#c5

However, I think it might be related to https://bugs.kde.org/show_bug.cgi?id=477607  since the treeview being broken and thinking some files are expandable files could cause problems.
Comment 8 David Edmundson 2023-11-28 10:28:23 UTC 
To reproduce:
 - enable selection mode (at least once) with the space key
 -         setStyle(QApplication::style());  calls once
 - change the qstyle in systemsettings
 - click on something

the previously set style is now dangling
Comment 9 Akseli Lahtinen 2023-11-29 16:00:44 UTC 
Git commit 697d1648b796b6ba5c08dc01a86ed2e324690abf by Akseli Lahtinen.
Committed on 29/11/2023 at 17:00.
Pushed by akselmo into branch 'master'.

Set style to nullptr before painting listview

Resolves any possible dangling pointers
if application style is changed after
toggling the selection mode
