Sentry Crash Report:

Description cwo 2024-06-20 13:24:48 UTC
Application: dolphin (24.07.70)

Qt Version: 6.7.0
Frameworks Version: 6.4.0
Operating System: Linux 6.5.0-41-generic x86_64
Windowing System: Wayland
Distribution: KDE neon Unstable Edition
DrKonqi: 6.1.80 [CoredumpBackend]

-- Information about the crash:
I was trying to drag & drop a file from Dolphin to Kolourpaint, and as the Dolphin window was covering where I wanted to drop the file, I pressed Alt-Tab.

Dolphin restarted and the second attempt worked. I have not done extensive testing to see what triggers this, and how reproducible it is.

Neon Developer Edition

The reporter is unsure if this crash is reproducible.

I am unable to reproduce this exact bug, however I get the following:

1. Open kolourpaint
2. Open dolphin
3. Move dolphin over kolourpaint so it covers the whole image area
4. Start dragging an image file from dolphin
5. Switch windows (alt+tab) to kolourpaint so that the image area is now shown
6. Drop the image on kolourpaint

For me, its being still dropped in dolphin itself. Dolphin pops back up and asks do I want to copy/move/link.
