If we go on using prefixes for the constants, than this constant should also
start with "kErrorEncryptedOnc..."

[Greg Spencer (Chromium), 2012/12/07 18:12:27]

Constant went away.

That overwrites the json error, as there is no return in the last if clause,
instead the new_root pointer is NULL.

[Greg Spencer (Chromium), 2012/12/07 18:12:27]

good catch.  Added return from last if.

   return new_root.Pass();
