[rspec-users] rspec hangs when used with QtRuby

Hello to everyone

I'm having trouble using RSpec to test code which uses QtRuby (both version 3 
and 4).

I noticed that, after upgrading from RSpec 1.0.5 to RSpec 1.0.8, some of my 
specs which used QtRuby caused spec (or rake, when used from a Rakefile) to 
hang indefinitly. After a bit of investigation, I found that the problem 
arose in the following situation:

* requiring Qt4 / Qt3
* creating a stub which stubs a method called :type

What I found particulary strange is that this happens even if I don't actually 
use Qt in the spec (directly or not). The following is the simplest example I 
could write which reproduces the problem:

  require 'Qt4'

  describe 'something' do

    it 'should work passing the :type parameter' do
      s = stub('x', :type => 'anything')


If I remove the first line, spec exits correctly with the message "1 example, 
0 failures". With the first line, instead, it hangs, and I have to press 
Ctrl+C to make it go on (of course, in this case it says: "1 example, 1 
failure"). If I use another mock framework (I tried with flexmock), then 
everythings works. If I replace :type with anything else in the call to stub, 
then everything works.

I tried searching google, this mailing list's archives and QtRuby forum, but I 
found nothing about this. Am I doing something wrong or is it a RSpec or 
QtRuby problem? I'm asking here because I think it's caused by RSpec (or by 
my wrong use of it), since it happened when I upgraded RSpec. If the issue is 
related more to QtRuby than to RSpec, please let me know and I'll ask in the 
QtRuby forum.

Thanks in advance
