Ruby doc errorr

   authenticated_test_helper.rb: m.

RDoc failure in
vendor/plugins/acts_as_authenticated/generators/authenticated/te
mplates/authenticated_test_helper.rb at or around line 113 column 4

Before reporting this, could you check that the file
you’re documenting compiles cleanly–RDoc is not a
full Ruby parser, and gets confused easily if fed
invalid programs.

The internal error was:

c:/ruby/lib/ruby/1.8/rdoc/parsers/parse_rb.rb:403:in get_read': Interrupt from c:/ruby/lib/ruby/1.8/rdoc/parsers/parse_rb.rb:485:inget_read’

get_tk' from c:/ruby/lib/ruby/1.8/rdoc/parsers/parse_rb.rb:2067:inparse_method
_or_yield_parameters’
Terminate batch job (Y/N)? y

this is the error when i run rdoc

any idea?
