I don't think that was the problem, because I have all the 
gst-plugins-xyz libraries installed, too.  The patch didn't change 
the result.  Perhaps someone else can check and possibly apply this 
patch (perhaps the patch is fine and it's a problem on my system :-/ )

For future reference, I'll copy the output I get when I try to run 
'lollypop'.  It looks like something goes wrong with the (py-)gobject 
for gstreamer:
