As mentioned in
http://developer.gnome.org/doc/tutorials/gnome-i18n/developer.html#plurals,
this way of handling plurals is broken for many locales. A way to solve
this is by using ngettext instead as mentioned in that document.
A simple code example of code using ngettext:

  g_printf (ngettext ("Found %d file.", "Found %d files.", nbr_of_files),
nbr_of_files);
