Bug#314289: ssh: unable to login after upgrade to 4.1p1-3

[Peter Schwindt <schwindt@ba-loerrach.de>]

Package: ssh
Version: 1:4.1p1-3
Severity: grave
Justification: renders package unusable


After upgrading to ssh 4.1p1-3 (including openssh-server and -client)
I'm not able to login via ssh anymore. Log follows:

-- snip --
debug1: Authentication succeeded (keyboard-interactive).
debug1: channel 0: new [client-session]
debug1: Entering interactive session.
debug1: Sending environment.
debug1: Sending env LANG = C
debug1: channel 0: free: client-session, nchannels 1
Connection to marwin closed by remote host.
Connection to marwin closed.
-- snap --

It looks like authentication is working fine but I'm logged out
instantly. Worked fine till some hours ago.
