Debathena wraps dpkg to set NSS_NONLOCAL_IGNORE=ignore (so that when dpkg tries to create new local system users, they don't conflict with Hesiod users):

From /usr/bin/dpkg.debathena:

#!/bin/sh
export NSS_NONLOCAL_IGNORE=ignore
/usr/bin/dpkg.debathena-orig "$@"

byobu attempts to trigger a profile reload on upgrade by trying to create a file for each user with an active screen session:

From /var/lib/dpkg/info/byobu.postinst:

# Notify users that they should reload their profile
DIR="/var/run/screen"
if [ -d "$DIR" ]; then
        for d in "$DIR"/*; do
                [ -d "$d" ] || continue
                touch "$d/$PKG.reload-required"
                u=$(echo "$d" | sed "s:^.*/S-::")
                chown $u "$d/$PKG.reload-required"
                chmod 700 "$d/$PKG.reload-required"
        done
fi

Unfortunately, because NSS_NONLOCAL_IGNORE means that non-local users don't exist, the byobu postinst attempts to chown files to nonexistant users:

I just observed a user who wasn't able to log in because he had exceeded his quota; he got as far as the zenity dialog telling him his quota was exceeded, and then the login session completely hung when he pressed the OK button in the dialog. The zenity window hung with the button depressed, and the login didn't continue. I had to walk him through sshing in from another machine to delete some files; that's not something that the average user is expected to be able to do.
