Comment 24 for bug 1584485

OK, I have verified that the trusty-proposed version fixes the reported issue.

The steps ran for verification:

1) Start an ubuntu Trusty container
2) cp /etc/apt/sources.list /etc/apt/sources.list.back
3) Disable the trusty-updates and trusty-security archives in /etc/apt/sources.list
4) sudo apt-get update
5) sudo apt-get install samba winbind libnss-winbind libpam-winbind
6) Set /etc/nsswitch.conf to : passwd: winbind compat
7) Restart the services
   7.1) sudo restart smbd
   7.2) sudo restart nmbd
   7.3) sudo restart winbind
8) cp /etc/apt/sources.list.back /etc/apt/sources.list
9) sudo apt-get update
7) sudo apt-get install samba winbind libnss-winbind libpam-winbind

The segmentation fault mentioned before is not experience,
