I'm unable to reproduce this.  Does this still happen for you?

Title:
  tar error when running make -f debian/rules binary

Status in “tar” package in Ubuntu:
  Incomplete
Status in “tar” package in Debian:
  New

Bug description:
  Binary package hint: dpkg

  Maybe this is a tar bug.  It gives an unsettling error message under
  dpkg.  One or the other should probably change.

  First noticed on 6.10 amd64 however can be reproduced on x86 version
  also.

  Steps to reproduce:

  apt-get source <almost any package>
  cd <where you build it>
  make -f debian/rules binary
  ...
  dpkg-deb: building package `whatever' in `someplace'.
  tar: -: file name read contains nul character

  For example:
  cd /usr/src
  mkdir login
  cd login
  apt-get build-dep login
  apt-get source login
  cd shadow-4.0.16
  make -f debian/rules binary
  ...
  dh_builddeb -plogin
  dpkg-deb: building package `login' in `../login_4.0.16-2ubuntu4_amd64.deb'.
  tar: -: file name read contains nul character

  From an 'strace -f' of the above:
  execve("/bin/tar", ["tar", "-cf", "-", "-T", "-", "--null", "--no-recursion"], [/* 20 vars */]) = 0

  
  which from the rest of the strace looks like the tar in question.  The "tar" manpage appears to support this usage.  However if I run the following
  script:

  #!/bin/bash
  # Script: breaktar.sh
  rm -f t1 t2 t3.tar
  cat <<EOF >t1
  some stuff
  EOF
  cat <<EOF >t2
  more stuff
  EOF
  printf "%s\0%s\0" t1 t2 |
  /bin/tar -cf - -T - --null --no-recursion >t3.tar

  
  I get:

  breaktar.sh
  /bin/tar: -: file name read contains nul character

  although oddly enough t3.tar has the expected contents.  The tar
  version on 6.10:

  $ tar --version
  tar (GNU tar) 1.15.91

  An older version of tar does not give this error message:

  $ tar --version
  tar (GNU tar) 1.15.1
  breaktar.sh
  (no error message)
