 It looks like `super` behavior is a bit different in 1.8 and 1.9. 
Please find the example below:

 class Base
   def foo
     puts "bar"
   end
 end

 module Override
   def foo
     puts "override"
     super
   end
 end


 class A < Base
 end

 class B < A
 end

 B.send(:include, Override)
 A.send(:include, Override)

 B.new.foo

 ruby 1.8.7 (2009-06-12 patchlevel 174) [i486-linux] output:


 override
 override
 bar


 and ruby 1.9.3dev (2010-05-26 trunk 28028) [i686-linux] output:

 ....
 override
 override
 override
 override
 override
 super.rb:9: stack level too deep (SystemStackError)


 Hope that helps.
