If you do ri of Rail’s option\_groups\_from\_collection\_for\_select, whose  
complete name is  
ActionView::Helpers::FormOptionsHelper#option\_groups\_from\_collection\_for\_select,  
then ri\_formatter.rb throws an error at line 18:

```
def draw_line(label=nil)
  len = @width
  len -= (label.size+1) if label
  print "-"*len <<< here

```

because len comes out to be negative (if width is set to 72).

The fix is trivial.

I can’t find any other way to report a bug except this forum.

HTH,  
Perry

Did you try the RDoc project on RubyForge?
