I'm sorry to bother you again... but I just tried it and it still
doesn't work for me:

Unhandled Exception: System.NullReferenceException: A null value was
found where an object instance was required
in <0x00090> 00 Gdk.Pixbuf:LoadFromStream (System.IO.Stream)
in <0x000aa> 00 Gdk.Pixbuf:.ctor (System.Reflection.Assembly,string)
in <0x000ca> 00 .Test:.ctor ()
in <0x00027> 00 .Test:Main (string[])

The only way I can get it to work is to take the null out of the
parameters and include the image in the current directory.

BTW... I am running this on a redhat 9 system with mono 0.24 and
gtk-sharp 0.9.

I didn't change your source code.
