ruby 1.8.7 (2009-06-12 patchlevel 174) [universal-darwin10.0]
<b>Class: String</b><hr>...

ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-darwin10.4.0]
:in `accept_rule': undefined method `>' for nil:NilClass (NoMethodError)

Adding an "|| 0" on the end of line 191 at least gets it to spit out
html; but, I didn't look any deeper to see where the rule's with nil
weight came from:
  #<struct RDoc::Markup::Rule weight=1>
  #<struct RDoc::Markup::Rule weight=1>
  #<struct RDoc::Markup::Rule weight=nil>
  :in `accept_rule': undefined method `>' for nil:NilClass (NoMethodError)

I see you filed a bug report but no patch. I will fix it when I have time.
