[gdome]reference counting again

[Chaoron <chaoron ludens elte hu>]

Hi!

I've got another code snippet. I've tried to only unref the first 
child, but it's not helped. Works the same with gdome_n_lastChild() 
instead. I could not find any error in my code. No idea about the 
solution. Compiled with gcc (2.95.2) on Debian Potato with gdome-0.7.2, 
libxml-2.4.22, glib-2.03. See the attached gdome-test2.c file.
