I know I'm replying to myself, but I figured out what causes gshadow to 
get corrupted.

Execute the following commands:
  tail /etc/gshadow         # to know what you started with
  groupadd sambashare
  tail /etc/gshadow
  useradd xyz
  tail /etc/gshadow
  usermod -G sambashare xyz
  tail /etc/gshadow

The usermod utility causes corruption in gshadow. The more users area 
added to the sambashare group, the more trashed gshadow becomes.

To remove the corruption :
  userdel -r xyz
  groupdel sambashare

I'm going to bugzilla this if its not in there already.
