  Target Milestone: ---

Application: dolphin (23.04.1)

Qt Version: 5.15.9
Frameworks Version: 5.106.0
Operating System: Linux 6.3.6-arch1-1 x86_64
Windowing System: Wayland
Distribution: EndeavourOS
DrKonqi: 5.27.5 [KCrashBackend]

-- Information about the crash:
While interacting with a custom application that requires you to drag and drop
files onto it, I found that dolphin crashed every time I selected the file
after a succesful drag and drop.

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
