This bug was fixed in the package samba - 2:3.4.0-3ubuntu3

samba (2:3.4.0-3ubuntu3) karmic; urgency=low

  * Fix FTBFS: fix libtalloc detection. (cherry picked from Debian)
    + debian/control: Add pkg-config as a dependency, needed to fix libtalloc detection
    + debian/patches/external-talloc-support.patch: fix the Makefile so it works
      when using external talloc instead of giving a missing-depend error.
    + debian/patches/autoconf.pach: Resurrect needed to fix the libtalloc errors.
    + debian/rules: build with --without-libtalloc and --enale-external-libtalloc
  * debian/patches/fix-crash-when-loading-interfaces.patch: Fix segfault when loading
    some wonky configuration files. (LP: #421419)
