PG 7.3.1 with ssl on linux hangs (testcase available)

since I moved from postgres 7.1 to 7.3 I get hangs when executing a
select on certaint rows with binary data using psql

The problem is reproducible and affects only single rows in the table .
The hangs happen only when I connect via network unsing psql -h
localhost template1

And the problem is gone, when ssl is switched off in postgresql.conf
But the problem seems to be on the client side, cause its the same using
a 7.1 server.

I have generated a testcase with 2 rows, one works the other not:

The table looks like this

create table testy (id integer, data bytea
);
  (I can send a dump of the table with the offending rows to anybody
interessted by mail -- its about 130 K )
  select * from testy where id=28162    --> works  select * from testy where id=28163    --> hangs + process goes up to
99% utilisation

The offending row is much larger, that might trigger.
  I use a debian system with:  postgresql                               7.3.3-1 client and server
