[Gtk-sharp-list] Current way of creating a Pixbuf from an RGB Array

If this has been fixed in February i assume that it's already in the 2.0
Preview Source release on 1st August 2008 ;-)

I am using the following Mono and GTK# Versions:

Mono 2.0 Preview 1
GTK# 2.12

Currently i am unable to use the SVN version because i can't access the Repo
from within the company, but will try it out when at home. Attanded you will
find a demo source which throws the Exception when creating the Pixbuf from
the Array.
