that makes sense, because some users aren't allowed to log in.  For
example: 
|  man:x:13:15:man:/usr/share/man:/bin/false
the man user can't log in.  the shell is /bin/false.

now that I can't explain.  But I have games and guest myself, although
I don't use CVS.  So my guess is it's not a bug and you've not been
hacked.
