Comment(by tar.gz):

 Thanks for the clarification. Indeed my testing was incomplete, $cat needs
 to be defined. The code that I am using successfully in 3.0.3 (in order to
 generate a breadcrumbs trail) looks like this:

  if ( is_single() ) {
  $cat = get_the_category(); $cat = $cat[0];
  echo(get_category_parents($cat, TRUE, ' &gt; ')); }

 The line that gets flagged in the error message is the line with
 ''echo(get_category_parents'' ... -- that's what brought me to believe
 that there was an issue with this function.

 It might very well be that there is a conceptual flaw in my code, but it
 was working until now.
