rkhunter-1.4.2-1.1.armv7hl (current in factory as of now)

# rkhunter --update

/usr/bin/rkhunter: line 7439: [: too many arguments

/usr/bin/rkhunter: line 7439: [: too many arguments
  Checking file i18n/zh.utf8                                 [ No update ]

This is caused by the command
grep '^[Vv]ersion:[0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]$'
/var/lib/rkhunter/db/i18n/tr
Binary file /var/lib/rkhunter/db/i18n/tr matches

This is unexpected output for the script.

This problem is probably upstream. I can't find the .src.rpm for factory
armv7hl.
