Bug#767731: /usr/bin/rkhunter: 13967: [: -ne: unexpected operator

[benoit@friry.net (Benoit Friry)]

Package: rkhunter
Version: 1.4.2-0.2
Severity: important

Bonjour,

Since upgrade to 1.4.2-0.2, I get cron errors:
/etc/cron.daily/rkhunter:
/usr/bin/rkhunter: 13967: [: -ne: unexpected operator

This line is:
if [ `${IPCS_CMD} -u 2>/dev/null | awk -F' ' '/segments allocated/ {print $3}'` -ne 0 ]; then

To compare with:
# ipcs -u 2>/dev/null

------ ?tats des messages --------

My default locale is French:
# cat /etc/default/locale 
#  File generated by update-locale
LANG="fr_FR.UTF-8"

I created a /usr/bin/rkhunter.new and forced LANG=C before line 13967,
adapted /etc/cron.daily/rkhunter, and I don't have error anymore.

I suggest using data from /proc if possible (I did not find how to get 
these data from there), or force LANG=C.

Thanks,
Benoit
