And the backtrace just keeps going like this forever; there seems to be infinite recursion being triggered via Plasma::Applet::removeInternalAction.


EXPECTED RESULT
Plasma doesn't crash
Comment 1 Nate Graham 2023-08-01 20:26:51 UTC 
Looks to be fixed already by https://invent.kde.org/frameworks/plasma-framework/-/merge_requests/837!
Comment 2 Fushan Wen 2023-08-02 01:13:39 UTC 
Git commit cd5e4ab9cdec8c610ed8e01df01ff488966dfa4e by Fushan Wen.
Committed on 02/08/2023 at 03:13.
Pushed by fusionfuture into branch 'master'.

Applet: fix crash after a widget is removed or disabled

In the connection with `QObject::destroyed`, there is no need to delete
an action again, otherwise there is a double delete.
FIXED-IN: 6.0
