Bug Description

I use last version (4.01-8) on Vivid. It is a fresh update, before that with same config, I had no error on Ubuntu 14.04.

Server is on Centos 6 and client is now Ubuntu 15.04. Quota is configured and works on server.
We have no problem with Ubuntu 14.04 clients, but with Ubuntu 15.04:

$ quota -v
Segmentation fault (core dumped)
$ quota -vi
$ quota -vA
Segmentation fault (core dumped)

$ apt-cache policy quota
quota:
  Installed: 4.01-8
  Candidate: 4.01-8
  Version table:
 *** 4.01-8 0
        500 http://fr.archive.ubuntu.com/ubuntu/ vivid/main amd64 Packages
        100 /var/lib/dpkg/status

Because this was fixed in 16.04 and 15.04 is no longer supported I am marking this as "Fix Released"
