[Rivet] issue with mkhtml complaining about ReadError

[Chris Pollard]

Hi Raghav,

I don't have this problem with yoda v1.6.0. Do you mind reinstalling the
latest version of yoda and seeing if it works? I'll let Andy chime in, but
I don't think there are big differences between your version of yoda and
mine, so performing a clean install of 1.5.9 may also do the trick.
