Comment (by bobbingwide):

 As a workaround for this problem I have coded something like
 {{{
   $category = get_term( $ID, 'category' );
   if ( is_wp_error( $category ) || is_null( $category)  ) {
     $catname = "Invalid category - please Delete ";
   } else {
     $catname = $category->name;
   }
 }}}
 which is almost exactly the same as I would have had to have written to
 handle the results from a 'fixed' version of get_the_category_by_ID().

 Given that you can get a fatal from echo get_the_category_by_ID( 0 ); then
 I would support either the deprecation of the function or some further
 work to make the function more useful as a template tag.
