Looks like you've got it sorted, but for the record: it's a bug in
glibc that causes a crash when a name service lookup is done and /lib
doesn't exist. Normally this isn't a problem but it causes problems
when a chroot'ed process does a name lookup.
The workaround is to create a /lib dir inside sshd's chroot (/var/empty
by default). The real solution is of course to upgrade to a glibc that
has the bug fixed.

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
