It would be nice to handle singular/plural here. In that case, please use
ngettext as mentioned in
http://developer.gnome.org/doc/tutorials/gnome-i18n/developer.html#plurals.
A simple code example of code using ngettext:

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