This bug should be fixed in the next debian-glibc 2.3.2.ds-14.

I committed with another simple way as follows:
dpkg -s $check 2> /dev/null | egrep '^Package:|^Status:' | awk '{if ($1
~ /Package:/) { package=$2 } else if ($0 ~ /Status: .* installed/ ) { print
package }}'

I reconsider it. If package is such an invalid state, daemons are not
