I guess you can workaround the bug until it gets properly fixed - by
opening the BigDecimal class. Last night I could not come with
anything reasonable though ;-)

class BigDecimal
   alias_method :old_round, :round
   def round(*args)
      if XXX
         self.class.new(YYY)
      else
         old_round(*args)
      end
   end
end

the problematic parts are XXX and YYY... ;-)
args[0] and self.exponent might be usable...

I haven't found any unit tests for BigDecimal, so if you create some,
please post them somewhere (I'm not sure where - possible choises are:
ruby tracker, http://rubyforge.org/projects/bfts/ tracker, ruby-core
mailing list)
