Does that particular Db have it's SYS schema ANALYZED? This should return no rows - if it does, then you can drop the stats for SYS and run this query again.

select table_name from dba_tables where last_analyzed is not null and owner = 'SYS';

The problem could be that partial/complete ANALYZE of the SYS objects is resulting in Queries-from-Hell. Queries against the DD are written for Rule and the stats forces the CBO to be used instead..
