[Kde-bindings] QtRuby + Ruby 1.9 and the kross/qtruby crash

[Cyrille Berger]

Hi

As I suspect the kross/qtruby crash was caused by some problem deep in some 
interraction between ruby's vm and Qt and memory pointers (as the fact that 
it doesn't crash on an 64bits computer).

So I decided to try ruby 1.9 (to get it build and running I had to patch 
QtRuby source and use the FindRUBY.cmake in attachement ). As far as I can 
see with Ruby 1.9 I don't get a crash with QtRuby and Kross on 32bits system. 
But unfortunately the connect function is also broken :(
