no sound after station changed (from playlist) on archlinuxarm (armv7h) with gstreamer 1.22.1

[solsticedhiver]

I have a playlist of radio stations.

Since I upgraded to gstreamer 1.22.1 on rpi3b running archlinux arm (32 bits/armv7h), when I change station, I got no sound, even tough the wbe ui says that the station changed.

In fact, from the verbose log, one can see that mopidy keeps on buffering for some unknwon reason.

This is not a network problem, because this happens when changing radio station.
If starting with station #1, it is ok. but station #2 fails. but if starting with station #2 no problme, but swithcing to station #1, this fails.

Downgrading to gstreamer 1.22.0 with gst-python and all gst-plugins packages, fixes the issue right away.

This is likely related to that OverflowError:

OverflowError: Python int too large to convert to C long                     
he above exception was the direct cause of the following exception:

More detailed logs with gstreamer 1.22.0 and then 1.22.1, doing the same sequence:

• starting mopidy
• load the playlist
• select the first radio, and wait it starts to play
• wait a few seconds
• switch to somafm/groove salad (12th on the playlist)

running GST_DEBUG_FILE=gstreamer.log GST_DEBUG=3 mopidy -v > mopidy.log 2>&1

mopidy-1.22.0.log
gstreamer-no-color-1.22.0.log

mopidy-1.22.1.log
gstreamer-no-color-1.22.1.log

1.22.0 works. got sound for 2nd radio after change
1.22.1 no sound for 2nd radio after change

Sounds bad but it's at the end of the file so possibly it came later and was missed in the 1.22.0 log?

seems to work so far with gstreamer 1.22.2 and python 3.11.
crossing- fingers. not sure
