c/p from issue1178:

Closing this bugreport. We never had any real issues with deborphan in grml-live 
(meaning: works as intended for us :)) and since even the deborphan version from 
current sid (v1.7.28.8) doesn't provide the --recursive option yet I don't think 
it's worth keeping this bug report in our BTS any longer.

Thanks && regards,
