Bug#685093: Postinstall script fatal error while upgrading

[Olaf Reitmaier Veracierta <olafrv@gmail.com>]

Package: libc6
Version: 2.11.3-3
Severity: serious
Tags: squeeze

While issuing "dist-upgrade" appears the following fatal error:

***
Preparing to replace libc6 2.11.2-10 (using .../libc6_2.11.3-3_amd64.deb) ...
cat: /etc/ld.so.conf: Is a directory
Unpacking replacement libc6 ...
Setting up libc6 (2.11.3-3) ...
tail: error reading `/etc/ld.so.conf': Is a directory
/var/lib/dpkg/info/libc6.postinst: line 76: /etc/ld.so.conf: Is a directory
dpkg: error processing libc6 (--configure):
 subprocess installed post-installation script returned error exit status 1
configured to not write apport reports
                                      Errors were encountered while processing:
 libc6
E: Sub-process /usr/bin/dpkg returned an error code (1)
**

After the error appear I commented the line 76 in /var/lib/dpkg/info/libc6.postinst:

    if ! grep -q '^include /etc/ld.so.conf.d/.*\.conf$' /etc/ld.so.conf ; then
        echo # 'include /etc/ld.so.conf.d/*.conf' >> /etc/ld.so.conf
    fi

Then apt-get install -f the packages installs but throws warnings
about "tail -f" over the directory  "/etc/ld.so.conf" fails
and certainly is a directory.
