[Kde-bindings] qtruby and active record in ruby 1.9

[Alex]

A few months back Stefano Crocco posted about the qtruby
incompatibility with active record.  I'm wondering if there has been
any work done to resolve this?

The posting is here:  http://lists.kde.org/?l=kde-bindings&m=129231601221959&w=2

The issue is still exists in the most recent gem version of qt ruby
[qtbindings (4.6.3.2)]
