Qt 4.6 behaves differently when "overloading" signals

[Michael Jansen]

That warning and behaviour is about 5 or six years old. I asked thiago about 
it some weeks before. You only see it now because it only appears in qt 
developer builds which we only started to use when switching to the qt git 
repo.

So i think the ... it worked with qt <4.6 may be unlikely. Are you really 
sure?
