Hmm, so it does.  It comes down to this:

! LaTeX Error: \DUrole undefined.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...                                              
                                                  
l.195 \renewcommand*{\DUrole}
                             [2]{ #2 }

Where the offending command is in Documentation/media/index.rst.  Mauro,
got an idea for what's going on there?
