User unable to purge gnunet-server

[Shane O'Sullivan]

A user in #ubuntu was recieved the error:
http://pastebin.com/Zp2w87Pz
when attempting to purge gnunet-server

when asking the user for the output of the following:
 cat /etc/passwd | grep gnunet && cat /etc/group | grep gnunet && cat /etc/group | grep gnunetdns

the user replied with: http://pastebin.com/pbY5Rmua
which showed evidence of 2 different user accounts with username gnunet being created.

I had the user manually run:
sudo deluser pavel gnunet

The error still occurred upon attempting to purge the package.

The user then manually ran:
sudo deluser gnunet

and was then able to purge the package.
