Nit: Operators go on the ends of lines, and this is also indented 11 instead of
4.

Done.

If you're not going to return NULL, places like
AutomaticProfileResetter::BuildEvaluatorProgramInput() shouldn't NULL-check.

Or just return NULL inside the scoped_ptr<> instead of returning an empty
dictionary.

[engedy, 2013/10/16 11:13:54]

Done. Not checking for NULLs anymore.
