[Kde-bindings] is it possible to use qtruby4 with ruby 1.9?

[Stefano Crocco]

Should it be possible to use qtruby4 with ruby 1.9? I just tried with the 
recently released ruby 1.9.1, but, although everything compiled, when I tried 
to use it, I got an horrible crash.

The procedure I followed to compile qtruby was the following (I'm describing 
it in case I forgot to do something):

cd kdebindings
mkdir build
cd build
cmake ..
ccmake .

Using ccmake, I changed the CUSTOM_RUBY_SITE_ARCH_DIR variable to 
/usr/local/lib/ruby19/site_ruby/1.9.1/i686-linux
and the CUSTOM_RUBY_SITE_LIB_DIR variable to
/usr/local/lib/ruby19/site_ruby/1.9.1

make
sudo make install

As I said, everything compiled and installed correctly. I then tried the 
following command:

ruby19 -rQt4 -e 'Qt::Point.new 2,3'

This produced a crash and the following output:

/usr/local/lib/ruby19/site_ruby/1.9.1/Qt/qtruby4.rb:2529: [BUG] unknown type

Can't qtruby be used with ruby 1.9 or have I missed something in the 
installation procedure?

Thanks in advance
