Party mode on Playlist crashes

Kodi 16.1 crashes when I try to run Party Mode on a playlist. Seems to work fine if I do party mode with the whole library.

This feature had been working perfectly, but once it started crashing, it’s very consistent.

Any ideas how to fix it?

(BTW, I noticed the problem with version 15; I upgraded to 16 but the crash persists,)

Saludos!
Fernando.
