Build issues with python 3.13 of quodlibet 4.6.0

[hannes101]

Steps to reproduce

During the preparations for fedora 40 there is a mass rebuild to check if the python packages can be built with python 3.13.

There are a couple of issues with quodlibet, which I think can be fixed rather easily.
The details can be found in the following bug report https://bugzilla.redhat.com/show_bug.cgi?id=2259638
`quodlibet fails to build with Python 3.13.03.

Hmm yeah

feedparser (cgi)

I think we're on a really old version, and I suspect that upstream will have fixed this ages ago, but can check

telnet

Options (not exclusive)

1. retire that plugin, I can't test it any more either.
2. Rewrite the telnet stuff using even lower level socket code (etc)
3. But at least it should catch the import error and fail just the plugin

[declension]

Looks like the feedparser issue is resolved upstream

Thanks, will check on updating python3-feedparser in fedora. It currently is at 6.0.10, so should be fixed, when this is updated. Of course this only goes for the feedparser error, the telnet one is still present.
Is this correct that this is the Squeezebox plugin? I am wondering how big the user base for this might still be, given that apparently these were discontinued to be sold in 2012, according to https://en.wikipedia.org/wiki/Squeezebox_(network_music_player)

Yes. Who knows. I wrote it for myself originally but no longer have that setup. But it's a strong DIY and alternative-hardware (RPi, Chromecast, etc) ecosystem when i last checked so might be nice to keep it alive.

The immediate build issues should be fixed - can we retest @hannes101 ?

[hannes101]

I also got python-feedparser updated in fedora, so yes I think it should be testable. Will try to build it soon.
