Which version of QtRuby are you using? I fixed this when the problem when it 
was first reported. Here is the code from qtruby.rb:

module Kernel
	alias_method :_exec, :exec
	undef_method :exec
	
	# Kernel has a method called open() which takes a String as
	# the first argument. When a call is made to an open() method
	# in the Qt classes, it messes up the method_missing()
	# logic to divert it to the Smoke library. This code
	# fixes that problem by calling the appropriate method based
	# on the type of the first arg.
	alias_method :_open, :open
	
	def open(*k)
		if k.length > 0 and k[0].kind_of? String
			_open(*k)
		else
			method_missing(:open, *k)
		end
	end
end

So it looks at the args passed to Kernel.open() and calls the standard ruby 
version if the first arg is a String.
