F-secure v1 client has trouble connecting to openssh-2.5.1p1

[Kevin Taylor]

I'm observing that mac clients using F-Secure ssh v1 client log into the
ssh server, and then the client just hangs with nothing on the screen.

In the SYSLOG file, I see this:

Accepted password for user from host port whatever

Packet integrity error (62 != 58) at session.c:350
Disconnecting: Packet integrity error. (34)

This is sshd running on IRIX 6.5.3f
