Poll : New Actions for Lyrion/Squeezebox integration

@psketch , or anyone else, already since last months release, I'm having some strange issues.
I have a morning routine which works as an alarmclock to start playing (current playlist is saved and emptied) a song randomly from a list of songs defined as variables.

Before starting to play, some announcements (time in a loop, current weather, today's calendar entries) are made.
While that wake-up track is playing, that saved playlist is added to the current one.
I see that saved playlist being added and after the wake-up track, playback continues.
So far everyhing is OK and this worked for years.

Quite soon the playback stops and the playlist is empty!?
I found this error which seems to be related:

Logger: pysqueezebox.player
Source: components/squeezebox/util.py:20
First occurred: 10:16:57 AM (2 occurrences)
Last logged: 10:26:49 AM

Timed out (5) waiting for playlist_urls to have value [{'url': "file:///mnt/zpool/MultiMedia/Music/Pop/Peter_Gabriel/New_Blood/cd2/10_-_Don't_Give_Up_(Instrumental).mp3"}]
Timed out (600) waiting for mode to have value stop

Does this makes sense and do you have any clue what is happening?

EDIT: multiple players are always synced and this topic seems to be similar.
