Bug#512410: openssh-server: sshd segfaults (suppose libc or libpam-mount related)

Package: openssh-server
Version: 1:5.9p1-5
Followup-For: Bug #512410

We've just started seeing this bug on multiple hosts with the latest
openssh server in testing. Our systems use Kerberos/LDAP for
authentication; using a Kerberos ticket SSH functions perfectly, but if
the user enters a password, sshd will throw a general protection fault.
