And the CTRL+C resulted in:

RDoc failure in
gems/1.8/gems/rails-1.1.6/lib/rails_generator/generators/components/controll
er/templates/controller.rb at or around line 10 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:

/usr/lib/ruby/1.8/rdoc/parsers/parse_rb.rb:368:in `column': Interrupt
        from /usr/lib/ruby/1.8/rdoc/parsers/parse_rb.rb:481:in `char_no'
