Should we close this as RESOLVED UPSTREAM, or can/should we work around it
here, too?

Easiest way to reproduce for me is:
- compact mode
- ctrl+f (search mode)
- search something
- go down
- search something else
* Boom

Been investigating further. Problem is that the delegate is being sent keyboard
events still after being destroyed.

This is the same issue as this:
https://bugs.kde.org/show_bug.cgi?id=381814

Just crashing in different places.
