Description of Problem:
kuser doesn't delete group entries from /etc/gshadow.

Version-Release number of selected component (if applicable):
kdeadmin-2.2-10
I've verified this behavior on my i686 workstation running 
kdeadmin-2.2.1-1 as well.

How Reproducible:
100%

Steps to Reproduce:
1. delete user
2. grep /etc/gshadow for user's primary group

Actual Results:
there is still an entry for the user's primary group in gshadow.

Expected Results:
no entries should remain in passwd, shadow, groups, or gshadow. all of the 
others are removed as expected. gshadow is the only one to contain an
entry.
