ORA-1858 Error issued for prompt table in 8.53, worked in 8.49

We are in the process of upgrading from 9.0/PT 8.49 to 9.2/ PT 8.53.  We have a custom page that contains a date field with a custom prompt view.  When clicking on the search glass in 9.2/8.53, we get the following error:

ORA-01858: a non-numeric character was found where a numeric was expected

The error references the prompt view.  The sql to the view is below:

SELECT START_DT

  FROM PS_TL_CALENDAR

WHERE PERIOD_ID = 'PSWEEK'

   AND START_DT BETWEEN (SYSDATE-90) AND (SYSDATE+90)

   AND start_dt >= '01-nov-2009'

  ORDER BY start_dt ASC

If I run the sql in sql developer, it does not abend and returns data.  The page functions in 9.0/8.49.  I traced both of them and the sql in the trace files is identical.  Both 9.0 and 9.2 are on the same version of Oracle.
