I just found the answer and I will post it here, perhaps it's useful for others.

It seems that libglade and gettext uses different environment locales.
The python gettext, which is used by the script to provide
localization of any string
except the ones inside the glade xml file, checks the 'LANG' env
variable to determine
the language to use.
The gtk.glade gettext implementation, which takes care of the strings
inside the glade
xml/widgets, checks the 'LANGUAGE' env variable.
So in order to have localization of *all* strings you must set them both.

If I start my app like this everything works well:
LANG=nl_NL at euro LANGUAGE=nl_NL at euro python myapp.py

However I feel it's a bug that gtk.glade doesn't check the LANG var as
the Python gettext
does. Whatever reason there is for only checking the LANGUAGE var I
think that if
the Python gettext checks LANG so must the (py)gtk.glade. IMHO.
