Bug#653587: brltty: initramfs hook broken: cp: cannot stat `/usr/lib/gconv': No such file or directory

[Christian Hofstaedtler <christian@hofstaedtler.name>]

Package: brltty
Version: 4.2-8+b2
Severity: grave
Tags: sid
Justification: renders package unusable

When enabling START_IN_INITRAMFS in /etc/default/brltty,
update-initramfs -u fails:

update-initramfs: Generating /boot/initrd.img-3.1.0-1-amd64
Installing BRLTTY into initramfs...cp: cannot stat `/usr/lib/gconv': No
such file or directory
E: /usr/share/initramfs-tools/hooks/brltty failed with return 1.
update-initramfs: failed for /boot/initrd.img-3.1.0-1-amd64 with 1.

I'd think the library paths have changed with the introduction of
multiarch.
Indeed /usr/lib/gconv doesn't exist on this machine, but there is this
 path: /usr/lib/x86_64-linux-gnu/gconv

Thanks,
