DrKonqi auto-attaching complete backtrace.
Comment 2 Marco Martin 2023-12-19 12:27:22 UTC 
I can reproduce it with same BT, but only in a particular way:

for me it crashes when i change the show vs disabled status of an applet, *and* i just click ok without having pressed apply beforehand

apply+ok or apply+cancel won't crash
Comment 3 Kai Uwe Broulik 2023-12-20 16:39:11 UTC 
Can reproduce by clicking OK. Wonder why the parentContext gets destroyed, we can see it being 0x0 in the backtrace.
Comment 4 Fushan Wen 2024-01-25 09:13:05 UTC 
The last visible changed signal comes from the header (SearchField), so if the content item (ListView) can be hidden before the header, the crash can be circumvented.

Comment 11 Nate Graham 2025-09-17 15:35:28 UTC 
With current git master, this is 100% reproducible for me by disabling or un-disabling the Media Player widget. Same backtrace.
Comment 12 Nate Graham 2025-09-19 14:38:47 UTC 
Additional detail: I can only reproduce it if I click "OK" after enabling or disabling a widget, but not if I click "Apply".

Still 100% reproducible for me.
