-- Information about the crash:
Plasma crashes when I reproduce music using Jellyfin. The crash only happens when there is an album art image, otherwise Plasma works as expected. A notification is spawned just before the crashes, but as it is not retained I do not know what it says. This is always reproducible and I have witnessed it on two different devices. The issue was not present with KDE Frameworks 5.103.0, so my uneducated guess is that something changed there.

The crash can be reproduced every time.

Does the issue go away if you disable (don't hide, disable) the Media Player widget in your Panel or System Tray?
Comment 3 Nate Graham 2023-04-04 19:37:01 UTC 
...Or if you disable Plasma Browser Integration? Or, if you're behind a proxy, if you disable the proxy?
Comment 4 Riccardo Robecchi 2023-04-08 08:29:56 UTC 
The bug appears to be fixed with Plasma 5.27.4. Thanks to whomever fixed it!
