Comment 1 nyre334 2024-04-16 14:14:22 UTC 
I can confirm

STEPS TO REPRODUCE
1. Open dolphin
2. DO NOT select any files or folders.
3. Press space to enter selection mode.


OBSERVED RESULT
Dolphin crashes.
EXPECTED RESULT
Dolphin enters selection mode.

From the tests I have done, the problem only exists on the version 24.02.2 of Dolphin and not on the 24.02.1.

Fix crash while entering selection mode with Qt6.7

`deleteLater()` on a non-existing object seems to cause a crash with
Qt6.7. This makes some sense but wasn't the case previously.

I didn't test this yet but it is a harmless change so if anyone can confirm we can IMO merge directly.

This was brought up in https://invent.kde.org/system/dolphin/-/merge_requests/764#note_920935, reported in the bug linked below, and the sentry crash reporting page also has a few dozen reports (https://crash-reports.kde.org/organizations/kde/issues/13589/?project=4&query=is%3Aunresolved&referrer=issue-stream&stream_index=1).

Dolphin 24.02 is also affected but we are already past the last bug fix release for it.
