add user help

I have just installed slackware (not sure what version or the kernel),  when I attempt to add a user to the system I get a segmentation fault error after it asks if the info i gave it is correct.  The only account on there so far is root.  Im new to the Linux world and couldnt really find to much documentation on troubleshooting.  Hope someone can help!   Thanks

You can do one of two things at this point.  1) reinstall adduser and maybe everything   2) add a user by hand.  This is done by
editing /etc/passwd   the format is this  
username:password:UID:GID:finger info (4 ,'s works fine):home directory:shell
If you open up /etc/passwd and copy the entry for root to the next line then change the username, UID, GID, and home directory then you will have a new user.  

Note:
  UID should be the highest UID in the file +1 the highest UID should be the last one in the file but you never know.
  GID needs to be a valid group id.  You can leave it as root's GID for now but you should probally change it later when adduser is back up.
  home dir. you will have to add the user to /etc/passwd and then
go create a home dir. where ever you said it would be (under /home I suspect) and make it owned by that user.  
    chown newuser.GID home_dir.  the GID for root should be 0 so
you can use that if you left the newuser GID the same as roots.

If I haven't forgoten anything you should now have a user named
username with a password the same as roots.  Now you can login
and change the password of your newuser.
