After Inatallation Rhythmbox with package rhythbox-plugins, a syntax warning appears in the terminal

[Ralph Hauck]

Making Standard (minimal) install Ubuntu 24.04.
After this, i install via terminal rhythmbox (also rhythmbox-plugins) and then i get the syntax warning for the plugin "lyrics", you can see in theattached file.
The pakages are:
https://launchpad.net/ubuntu/+source/rhythmbox/3.4.7-2ubuntu6
https://launchpad.net/ubuntu/noble/amd64/rhythmbox-plugins/3.4.7-1ubuntu1

So, i don't use the lyric functions, for me everything works (Radio and so on).
I cannot assess the effects on lyrics.

Thank you!

Best Regards
Ralph
