here is the stderr output for man -d man:
I can't reproduce this at all in an etch system, having set up a locale
matching yours. Can you reproduce this every time?
Could you please run:
cd /usr/share/man/es
zcat /usr/share/man/es/man1/man.1.gz > $HOME/zman123456
zsoelim $HOME/zman123456
... and see if that crashes in the same kind of way, with signal 11?
Yes, it does (now that I see the output, I realize that may be you want
to know I access the shell via ssh):

I'm willing to spend some time debugging this, but you're running
oldstable rather than the current stable and I've made eight upstream
releases since then fixing really quite a large number of bugs, so I'm
not going to keep this as a release-critical bug forever; I'm leaving it
that way for now on the off-chance that this bug is still present
somehow.
Thanks for your attention, and sorry for the inconvenience. I'm sure
you'll do what is most appropiate.
