Absurd permissions on /etc/depmod.d, /etc/modprobe.d crash apport-retrace

$ dpkg -c kmod_9-2ubuntu3_amd64.deb | grep '\.d/$'
drwxr-xr-x root/root 0 2012-10-30 17:26 ./lib/modprobe.d/
drw-r-xr-x root/root 0 2012-10-30 17:26 ./etc/depmod.d/
drwxr-xr-x root/root 0 2012-10-30 17:26 ./etc/init.d/
drw-r-xr-x root/root 0 2012-10-30 17:26 ./etc/modprobe.d/

This causes apport-retrace to die during cleanup as follows:
