sshd not giving me a tty

[Thomas Klausner <wiz%NetBSD.org@localhost>]

Hi!

Since my amd64 update from 4.99.58 to 4.99.60, sshd doesn't give me a
tty.  Client hasn't changed. Server now has openssh 5.0.

ssh -vv hiro gives:

...
Password:
debug2: input_userauth_info_req
debug2: input_userauth_info_req: num_prompts 0
debug1: Authentication succeeded (keyboard-interactive).
debug1: channel 0: new [client-session]
debug2: channel 0: send open
debug1: Entering interactive session.
debug2: callback start
debug2: ssh_session2_setup: id 0
debug1: channel 0: request pty-req
debug1: channel 0: request shell
debug2: fd 4 setting TCP_NODELAY
debug2: callback done
debug1: channel 0: open confirm rwindow 0 rmax 32768
debug1: channel_free: channel 0: client-session, nchannels 1
Connection to hiro closed by remote host.
Connection to hiro closed.
debug1: Transferred: stdin 0, stdout 0, stderr 71 bytes in 0.0 seconds
debug1: Bytes per second: stdin 0.0, stdout 0.0, stderr 2210.3
debug1: Exit status -1

Adding '-t' to ssh's option doesn't change a thing.

ssh -vv hiro bash gives:
Password:
debug2: input_userauth_info_req
debug2: input_userauth_info_req: num_prompts 0
debug1: Authentication succeeded (keyboard-interactive).
debug1: channel 0: new [client-session]
debug2: channel 0: send open
debug1: Entering interactive session.
debug2: callback start
debug2: ssh_session2_setup: id 0
debug1: Sending command: bash
debug1: channel 0: request exec
debug2: callback done
debug1: channel 0: open confirm rwindow 0 rmax 32768
debug2: channel 0: rcvd adjust 2097152

and I can type and get results.

ssh -tvv hiro bash gives:

debug1: Authentication succeeded (keyboard-interactive).

Any ideas?
If you need more debugging output, please let me know.
