ubuntu-defaults-builder: all builds fail

The problem:
It looks like all iso-builds fail. I've tried both the Dutch customisation package which worked before, and the example package. Both builds fail with "E: config/chroot_local-hooks/00_language-support failed (exit non-zero). You should check for errors."

How to reproduce: try to build the example package using

/usr/share/doc/ubuntu-defaults-builder/examples/make-example
ubuntu-defaults-image --package ./defaults-builder-test_0.1_all.deb --components main,restricted,universe

I will attach the log of the build for the example package.
