-- Information about the crash:
KMail crashes after opening the Find Action... dialog — regardless if from 'Help' menu or by 'Ctrl' + 'Alt' + 'I' shortcut.

Most of the time the dialog appears, and right away KMail crashes.
Sometimes though, the dialog opens properly — showing text input field and dropdown list of default suggestions. If I then close the dialog by pressing the `Esc` key, KMail is otherwise unaffected. However, trying to type anything or even hovering the mouse over the dialog crashes immediately.

I believe there is some improvement from the first time I discovered the issue a couple of months ago (unfortunately couldn't report it back then). If I remember correctly — it used to always crash on invoking the dialog. Now, it sometimes does display the dialog, although is never functional — i.e. crashes (but is dismissable) as described above.

Operating System: Fedora Linux 37

The crash can be reproduced every time.
