> this what analyze says:

the following output looks like from EXPLAIN, not from EXPLAIN ANALYSE,
the actual timings, loops etc are missing. Could you please repost?

> "Index Scan using mytable_the_geom_gist on mytable  (cost=0.00..4.95 rows=1 width=13)"
> "  Index Cond: ....
> "  Filter: ...
> 
> "Index Scan using mytable_bbox_gist on mytable  (cost=0.00..4.95 rows=1 width=13)"
> "  Index Cond: (...
> "  Filter: (...

Also some version/platform information would help. Could you please post
the output of 
 select postgis_full_version();
and 
 select version();

Regards,

        Frank
