This seems to be a conflict between GTK+ and R. Apparently, GTK+ sets the
locale by itself. There is a way to prevent GTK+ from doing that. I will
release a hotfix for RGtk2 soon and we'll see if it fixes it. I just need to
run gtk_disable_setlocale() before gtk_init_check().
Thanks for reporting this,
Michael
