The only thing I see you are missing is the check for is_default. If you have any other traces running on the instance you may be picking up that one. Try this:

DECLARE @path NVARCHAR(260);

SELECT @path = REVERSE(SUBSTRING(REVERSE([path]), CHARINDEX('\', REVERSE([path])), 260)) + N'log.trc'

FROM sys.traces

WHERE is_default = 1;

SELECT *

FROM sys.fn_trace_gettable(@path, DEFAULT) t

LEFT JOIN sys.trace_events te ON t.EventClass = te.trace_event_id

WHERE t.EventClass = 104

ORDER BY StartTime DESC;
