Im having this issue as well.

postgres 9.0 with streaming replication setup.
pgpool pgpool2_3.0.4-1_i386.deb on ubuntu 10.04

when I just have pgpool pushing to one backend it works.

when I turn on load balanceing, master/slave and set master_slave_sub_mode to 
'stream' .

if I have these turned off it works fine. I've got ssl disabled in pgpool and 
the two dbs and authentication set to trust.

hope this helps
