Nit: This formatting is wacky.  How about:

  base::string16 min_string(description, 0, chop_index);
  if (chop_index == base::string16::npos) {
    // Show at least 4 characters plus an ellipsis.
    min_string = gfx::TruncateString(description, 5, gfx::WORD_BREAK);
  }

+          gfx::TruncateString(description, 5, gfx::WORD_BREAK)
+          : description.substr(0, chop_index));
   base::i18n::AdjustStringForLocaleDirection(&min_string);
   return min_string;
 }
 
 }  // namespace location_bar_util
