Description Gatg 2025-12-20 23:53:52 UTC 
Application: dolphin (25.04.3)

ApplicationNotResponding [ANR]: true
Qt Version: 6.8.2
Frameworks Version: 6.13.0
Operating System: Linux 6.12.57+deb13-amd64 x86_64
Windowing System: Wayland
Distribution: Debian GNU/Linux 13 (trixie)
DrKonqi: 6.3.4 [CoredumpBackend]

-- Information about the crash:
I have kdeconnect on my phone (1.34.4) and on Debian trixie (KDE Plasma v6.3.6 and Frameworks v6.13.0).
I can see my phone in de Devices section in the side panel of Dolphin, and navigate it's filesystem through this kdeconnect:// uri.
If I select an important amount of files under this uri (e.g. >300) and try to do something with them (as move, or right-click), dolphin (v.25.04.3) freezes completely and eventually the window greys to "(Not responding)". If I try to close it it offers to force close, which triggered this crash.
If it's still a reasonabel amount of files (<250?), after been frozen for a minute or more, it can manage to finish and show the menu.

The crash can be reproduced every time.

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

Comment 1 TraceyC 2026-01-22 15:28:37 UTC 
Thanks for the bug report. Unfortunately, these versions of Dolphin and Plasma are no longer maintained by KDE. Debian advises users to not submit bugs upstream (https://www.debian.org/Bugs/Reporting). It's possible that the bug exists only in Debian at this point. 

Could you report the bug to Debian using the report bug utility (https://packages.debian.org/stable/utils/reportbug)? If necessary, the maintainer of the package will forward the bug upstream.

Thanks for understanding.
