In Estuary you click on Music -> titles -> then left and there is  switch to start Party Mode This should load a bunch of song ins random and then play.

Right thanks - so for me that is working (I'm using MySQL), and I have 7384 songs in my Music library.

How many songs do you have in your library (you can run texturecache.py stats for a breakdown)?

Are you using MySQL or SQLite? At what point is Kodi crashing - while the "Filling glasses/drinks..." dialog is visible, or once the list of songs appears (I see a list of 10 songs), or while playing back one of these songs (maybe while switching tracks?)

I have a feeling something like this may have come up before - Kodi can be inefficient about how it handles large playlists, particularly when pumping out JSON playlist updates to consuming clients. If you're using Yatse then try it without Yatse running _anywhere_, on _any_ device - Yatse can be a very "chatty" application, constantly hammering Kodi (potentially multiple Kodi clients) for status updates it could instead receive via JSON event notifications (at least, that's how it used to work when I took the time too look at it some time ago, maybe it's improved since then).

Did you identify the first build when Party Mode stopped working? I wonder if a debug-enabled build will provide a more useful crash-log (I'll see about uploading a debug build overnight).
