[SOLVED] moOde 9.0.5 and 9.0.7: Adding radio station to playlist does not work

[the_bertrum]

@TheOldPresbyope , @Tim Curtis , @Nutul I just sent you via PM a movie where I explain how to reproduce the issue, but also how you can workaround it.
As mentioned earlier, I bet on a playlist file locking issue, caused by MPD locking the file when scanning the PL folder.
The reproducer scenario works consistent on my 3 PIs.

Just so I'm sure I've got the case straight in my head, you get this error when:

A stored playlist is loaded into the queue, you start to play that playlist, then you try to re-add to the playlist a station that is already on the playlist?

Or


A stored playlist is loaded into the queue, you start to play that playlist, then you try to add a new station to the playlist?

And you get the error when using the three dot on a station and selecting "add to playlist" but not when adding a station to the queue then saving the queue as a playlist?

Hi Robert,

It's just about adding radio stations to whatever playlist. This causes an issue when 

In this video you can see what happens and how to reproduce the issue. Turn on the volume, as I explain the steps.

Well the video is very clear, but even sticking to the radio stations you are using in your test I can't repro either.  There must be something very specific in your system that's tripping this up.  Do you have any packet inspection or such like going on in your LAN?
