MPD error

[TheOldPresbyope]

Well, I tested positive for COVID19 antigens when we got to Virginia Beach (5 hour drive), so we turned around and came home (yup, 5 hour trip again). Now in day 5 and still feeling crappy, so this is just a teaser. Thankfully my SO is still testing negative.

I seem to be able to force the "MPD Error: JSON.parse" popup easily using the Mozilla Firefox desktop browser on my Linux laptop, in the Windows 10 guest O/S on same, and the Firefox app on my Android phone. While in the moOde playback view, go to m>Power>Restart and watch the screen as moOde restarts. First the expected RECONNECT popup appears, then for a while the MPD Error message keeps repeating.  Finally, normal operation is restored. Or something like that. I don't know if it's necessary to have tracks in the queue; I did.

This behavior doesn't occur with the Google Chromium browser on the above platforms or with Microsoft Edge in the Windows 10 Guest O/S. It doesn't occur with any browser on my iPad, either, but that's probably due to their underlying common engine.

Here's a long snippet of the Firefox console output while this is going on
