           Summary: Dolphin crashes when draggin 1000+ files to share on
                    external app

           Product: dolphin
           Version: 23.04.2

  Target Milestone: ---

Application: dolphin (23.04.2)

Qt Version: 5.15.9
Frameworks Version: 5.106.0
Operating System: Linux 6.3.6-200.fc38.x86_64 x86_64
Windowing System: Wayland
Distribution: Fedora Linux 38 (KDE Plasma)
DrKonqi: 5.27.5 [KCrashBackend]

-- Information about the crash:
This is a fresh Fedora KDE 38 install. When I try to share more than around
1300 files via selecting them and dragging onto another app, the moments I
start to drag them, dolphin crashes.

Locale: All TR_tr except language on Regional Settings tab on system settings.
All of the themes are Breeze/default.
encrypted btrfs root with compress-force=zstd:15
openSUSE TW didn't have this issue. Fedora issue?

I select the files: FINE
I click: FINE
I hold the mouse button on the items without dragging: FINE
The moment I start dragging: CRASH

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Aborted
