attr_size() is in points / PANGO_SCALE, so you are asking for
an approximately 0.1 point font.

The default range for a newly created attribute is 0-0. So you
need:

 text_size->start_index = 0;
 text_size->end_index = G_MAXUINT;

and the same for the weight. (pango_layout_set_font_description()
is probably considerably easier if you want to affect the
entire layout. You can use partial font descriptions like 
"Bold 10")
