Problem with streaming replication over SSL

I have streaming replication configured over SSL, and
there seems to be a problem with SSL renegotiation.

This is from the primary's log:

2012-11-06 00:13:10.990
CET,"replication","",5204,"10.153.109.3:49889",509843df.1454,10,"streami

unexpected record",,,,,,,,,"walreceiver"

2012-11-06 00:13:10.998
CET,"replication","",5204,"10.153.109.3:49889",509843df.1454,12,"streami
ng 1E3/76D64000",2012-11-05 23:55:27 CET,4/0,0,LOG,08006,"could not send
data to client: Connection reset by peer",,,,,,,,,"walreceiver"

This is what the standby has to say:

2012-11-06 00:13:11.001 CET,,,26789,,509843df.68a5,2,,2012-11-05
23:55:27 CET,,0,FATAL,XX000,"could not receive data from WAL stream: SSL
error: sslv3 alert unexpected message
",,,,,,,,,""

This is PostgreSQL 9.1.3 on RHEL 6, openssl-1.0.0-20.el6.x86_64,
kernel 2.6.32-220.el6.x86_64.

After that, streaming replication reconnects and resumes working.

Is this an oversight in the replication protocol, or is this
working as designed?
