 Downgrading py27-mistune to 0.8.4 does fix the problem for me. (Not saying
 that's what we should do necessarily, just confirming that it's the same
 issue.)

 > py-mistune was updated to 2.0.2 in April, reverted to 0.8.4 the next
 day,

 because it broke py-nbconvert

 but nobody who had the downgraded 0.8.4 received the 2.0.4 update because
 the `epoch` was decreased.
