[Bug 797157] [NEW] mount.nfs segfault error 4 in libc-2.13.so

[Merelin]

Public bug reported:

mantonyan at mantonyan:~$ lsb_release -rd
Description:	Ubuntu oneiric (development branch)
Release:	11.10

mantonyan at mantonyan:~$ apt-cache policy libc6
libc6:
  Installed: 2.13-6ubuntu2
  Candidate: 2.13-6ubuntu2
  Version table:
 *** 2.13-6ubuntu2 0

mount.nfs should mount nfs shares both with "sudo mount -t nfs" and with autofs. Neither of the two is operational.
One of the recent oneiric updates broke mount.nfs:
