Comment(by johncoswell):

 The error message: get_object_vars() expects parameter 1 to be object,
 null given in wp-includes\taxonomy.php on line 335

 The function get_category() is being called with $object set to ARRAY_A.
 If the requested category ID that is passed to get_category(), which is
 subsequently passed to wpdb::get_row(), does not exist in the database, or
 some other failure occurs within wpdb::get_row(), wpdb::get_row() can
 return a non-object value such as null. When the code falls through to the
 section returning the output, and ARRAY_A or ARRAY_N is provided as
 $object, this non-object value will be passed to get_object_vars(),
 raising the warning. This warning is not raised in any other state for
 $object, as those cause $_term to be returned untouched.
