Ironruby core - Nov 2009 - IronRuby 0.9.2 bug - super(.S, 1*&):433 @1 not supported on foreign meta-objects

I have the following code, which used to work under IronRuby 0.9.1 and
earlier

class Object
  def method_missing(sym, *args, &block)
    if sym.to_s =~ /blah regex/
      # do stuff
    else
      super # call through to underlying ruby method_missing
    end
  end
end

Under 0.9.1 this worked across the board, and under 0.9.2 it works for most
objects, but suddenly for COM objects it''s throwing an exception on the
call
to ''super''

Repro code:

load_assembly "microsoft.office.interop.word"
word = Microsoft.Office.Interop.Word.ApplicationClass.new
word.fdsfgdsf
System::NotSupportedException: super(.S,1*&):482 @1 not supported on foreign
meta-objects
        from (irb):12:in `method_missing''
        from (irb):16
        from C:/Dev/TEST/ruby/lib/ruby/1.8/irb.rb:150:in `eval_input''
        from :0:in `eval''
        from C:/Dev/TEST/ruby/lib/ruby/1.8/irb.rb:263:in
`signal_status''
        from C:/Dev/TEST/ruby/lib/ruby/1.8/irb.rb:147:in `eval_input''
        from C:/Dev/TEST/ruby/lib/ruby/1.8/irb.rb:146:in `eval_input''
        from C:/Dev/TEST/ruby/lib/ruby/1.8/irb.rb:70:in `start''
        from C:/Dev/TEST/ruby/lib/ruby/1.8/irb.rb:69:in `start''
        from C:/Dev/TEST/ruby/bin/iirb:13
        from :0:in `loop''
        from :0:in `catch''
        from :0:in `catch''

I''d be more than happy to work around it by not calling super if the
object
is a "foreign meta-object", but how can I tell that?

Cheers, Orion
