Fatal: Object could not be converted to string taxonomy.php:925

[apokalyptik]

The problem occurs when $parent is an object and not an integer as expected. The patch I'm including handles both possible cases as I'm not entirely sure if $parent should *always* be an integer, *always* be an object, or whether both types are acceptable here (I'm not familiar enough with the taxonomy code.) The first 2 possibilities warrant more elegant fixes than this.
