Confirmed fixed.

$ mkpasswd -l -u cwilson
cwilson:unused:1036:513:cwilson,U-VMWARE-XP\cwilson,S-1-5-21-3395897280-1512205858-4128055458-1036:/home/cwilson:/bin/bash

$ mkpasswd
<... output, but no segfault ...>

Emphasis on theoretical. :-(

While this
$ mkgroup
< ... output ...>

doesn't segfault, the following:

$ mkgroup -l -g Users
mkgroup (519): [2220] The group name could not be found.
Users:S-1-5-32-545:545:

is very odd. It *did* find the Users group, and printed the output --
but also printed an error message.

$ mkgroup -l -g nonexist
mkgroup (391): [0] The operation completed successfully.
 (nonexist)
mkgroup (519): [2220] The group name could not be found.

NOTE: this is my debug build of current CVS.
