MusicBox 0.5.1. RC2 autoplay not working anymore?

I have just replaced my 0.5.1 RC1 installation with RC2 (clean install). But now the autoplay feature doesn’t seem to work. Could it be that autoplay is somehow changed or broken in RC2?

My settings are:
autoplay =
autoplaywait = 15

I used the same settings in RC1.

BTW, I entered the URL directly into settings.ini because the webinterface doesn’t allow URL’s > 40 characters.

Otherwise: I’m very happy with MusicBox. Thanks for your great work!

Edit: Autoplay is working now after increasing the autoplaywait parameter to 30.
