Bug 513821

Application: plasmashell (6.5.4)

ApplicationNotResponding [ANR]: false
Qt Version: 6.10.1
Frameworks Version: 6.21.0
Operating System: Linux 6.14.0-37-generic x86_64
Windowing System: Wayland
Distribution: KDE neon User Edition
DrKonqi: 6.5.4 [CoredumpBackend]

-- Information about the crash:
Plasmashell crashed unexpectedly during normal desktop usage.

The crash happened shortly after I logged in, following several hours of sleep/suspend. After resuming, everything appeared normal at first. The last action I performed before the crash was dragging and dropping a file from the Dolphin into WhatsApp Web to send it.

However, I am not completely sure that the drag-and-drop action was the direct cause of the crash, as it is only the last interaction I remember before plasmashell stopped responding/crashed.

I have not observed this issue consistently, and I cannot yet reliably reproduce it. I am reporting this in case it is related to plasmashell's handling of drag-and-drop operations or resume-from-suspend state.

The crash can be reproduced sometimes.
