The problem appears when the image has been built using libc6-udeb
version 2.7 and a libc6-udeb 2.9 is downloaded and unpacked. The new
glibc is not fully usable until other glibc udeb packages, namely
libnss-dns-udeb and libnss-files-udeb are unpacked.

The segfault is caused here by using libc6 2.9 with a libnss-dns version
2.7.
