Attempting to poweroff from a sato image on atompc as the xuser results in a segfault:

$ sudo /sbin/poweroff
...
Password:
Segmentation fault

I'm nervous about the cause of this, we need to investigte...
Comment 2 Ross Burton 2013-04-11 13:42:47 UTC 
Confirmed.  Odd.  Also, "sudo ls" segfaults.

Appears to be caused by xuser having a locked account in /etc/shadow:

xuser:!:15806:0:99999:7:::

su'ing to root and setting a password lets xuser attempt to sudo ls (which then fails as xuser isn't in /etc/sudoers)
Comment 3 Richard Purdie 2013-04-11 13:52:03 UTC 
Is this related to the crypt issue we had recently?
Comment 4 Ross Burton 2013-04-11 14:37:35 UTC 
Yes.  Fixed locally.
