Issue streaming with mps-youtube

Hi,

I seem to be having some problems streaming videos with mps-youtube on Trisquel 8. I can download videos and play them with mpv just fine; however, whenever I try to stream, I get errors such as the following:

Traceback (most recent call last):

It looks like the problem is something to do with the Python 3 installation; however, according to Synaptic, Python3 seems to be installed. Although, under 'dependencies' for mps-youtube, 'python3:any' is listed in italics. Could that be part of the problem?
