PG 7.0 crash on SELECT

Issuing the followin SELECT crashes PG 7.0:

auction=# SELECT a.id,a.title,a.id,(select CASE WHEN a.stopdate < 'now' THEN 'closed' ELSE 'open' end) as status,to_char(a.time,'DD-MM HH24:MI'),b.price FROM auction* a, bid b WHERE a.id = b.auctionid AND b.login = 'mito2';
pqReadData() -- backend closed the channel unexpectedly.       This probably means the backend terminated abnormally       before or while processing the request.
The connection to the server was lost. Attempting reset: Failed.
!# \q

Apparently PG doesn't like the (SELECT CASE ... ) statement, until I
added it everything went well. 

Here are the table descriptions:
                              Table "auction" Attribute   |   Type    |                     Modifier
