Description stactk49 2025-01-28 20:28:17 UTC
Application: plasmashell (5.27.5)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.0-28-amd64 x86_64
Windowing System: Wayland
Distribution: Debian GNU/Linux 12 (bookworm)
DrKonqi: 5.27.5 [CoredumpBackend]

-- Information about the crash:
Steps to reproduce:

1. Click the sound icon on the panel.
2. Select the "Applications" tab
3. Select an application with an active audio stream.
4. Adjust the application's volume slider.
5. Plasmashell crashes intermittently during or shortly after this action. The screen goes black for a few seconds then the desktop reloads. Most open applications are unaffected, but any running audio or video in the browser needs to be restarted.

It does not happen all the time, and you may have to adjust multiple sliders to trigger the crash, but it sometimes only requires one to be moved. In my tests, I adjusted the sliders for VirtualBox, Brave Browser, and the speech-dispatcher-dummy.

Other information about the system:
OS: Debian Stable
Qt Version: 5.15.8
Kernel: 6.1.0-28-amd64
Platform: Wayland
Sound: Pulseaudio 16.1

The reporter is unsure if this crash is reproducible.

Comment 2 Bug Janitor Service 2025-01-28 20:33:39 UTC
Thank you for the bug report!

Debian advises users to not submit bugs upstream (https://www.debian.org/Bugs/Reporting), and Plasma 5.27.5 is no longer eligible for support or maintenance from KDE. It's possible that the issue 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!

Thanks again!
