I have located a problem which arises I think when LC_ALL is not set
(the actual circumstance I triggered by setting LANG to a language not
installed):

This is a pretty obscure case, but I guess some small tweak could fix
it? I have installed en_US now, but I can test as follows.

address@hidden:~/local/bin$ export LANG=pt_BR.utf8 
address@hidden:~/local/bin$ ./denemo

(process:7073): Gtk-WARNING **: Locale not supported by C library.
        Using the fallback 'C' locale.
