Title:
  lightdm-gtk-greeter segfaults in get_user_iter when adding a new user

Status in Light Display Manager:
  Fix Committed
Status in “lightdm” package in Ubuntu:
  Fix Released

Bug description:
  Steps to reproduce with lightdm-gtk-greeter 0.9.2:
  1) Switch to another vt or login through ssh
  2) sudo adduser someusername
  3) lightdm-gtk-greeter will crash

  The segfault occurs when user_changed_cb is triggered. When a new user
  is added, the user is appended to the end of the list, so when
  user_changed_cb calls get_user_iter, it will search through every row
  before finally finding the user at the end. However, the name for the
  "Other..." user is NULL, so when strcmp is called, the greeter
  crashes.
