Are you setting language tags on your text? (See
gtk_get_default_language()). If you don't set a language tag, GTK+ is
going to leave enough spacing for "any" language in many cases.

There are also some issues with pango_ft2_render_layout(); see:

 http://bugzilla.gnome.org/show_bug.cgi?id=105292

But unless you are setting the spacing attribute, shouldn't make a 
difference.
