it looks your version of rdoc (4.0.1) new. @thetinman indicated, may want bump ruby version 1.9.x or 2.0.0 if possible.

alternatively, try removing 4.0.1 , installing 3.12.2, recent 3.x variant on rubygems.

i dug source code determine rdoc attempting marshal.load cache file. perhaps want clear cache , re-run rvm docs generate-ri ensure cache encoding accurate.
