backtrace from drkonqi

I'll get some more specific reproduction steps later, but the jist of it is that I think I was in edit mode on a new page, when I deleted it, and attempted to navigate back to the Overview page. There was a dropdown sensor selection that was incorrectly still open, covering up the left pane. Then I closed the app, which produced a crash.

Comment 2 Marco Martin 2021-05-24 09:26:16 UTC 
looking at the backtrace it seems that the connection between full and updateitemvisibility is triggered anyways even if was manually disconnected?
