[Koha] Debian packages, Squeeze and updated libyaz

[Robin Sheat]

Recently Debian updated their zebra-related stuff in Squeeze, and
dropped libyaz3 in favour of libyaz4. This meant that I spent some time
trying to work out why zebra would work on the production system (which
I was being conservative about updating) and not my newer test systems.

It turns out that the version combinations currently in Debian make
Zebra quite unhappy, and it will segfault. You won't see this happen if
you run the rebuild_zebra.pl script, but you will get this if you run it
with -v:

11:18:31-02/08 zebraidx(12790) [log] enabling shadow
spec=/var/lib/koha/library/biblios/shadow:4G
11:18:31-02/08 zebraidx(12790) [log] cache_fname
= /var/lib/koha/library/biblios/shadow/cache
11:18:31-02/08 zebraidx(12790) [log] dir /tmp/qKmpRDFzQd/biblio
11:18:31-02/08 zebraidx(12791) [log] zebra_start 2.0.43
abd433d1a315576cf1f4a53f2c70365f9a76477f

(the segfault occurs where the PID changes from 12790 to 12791.)

And then, several lines later:
11:18:31-02/08 zebraidx(12791) [warn] previous transaction didn't reach
commit

and nothing in zebra will have been updated.

Fortunately, the version in the indexdata.dk repository doesn't suffer
from this, so if you're using the Debian Koha packages I suggest
performing the steps outlined here:
