Could you try building with an updated version of the patch I've
attached? It's a bit of a stab in the dark but I've fixed a potential
case where stdout might get accidentally closed.

Title:
  lightdm (1.2.3-0ubuntu2.6) 100%/high cpu usage

Status in lightdm package in Ubuntu:
  Confirmed

Bug description:
  Since updating lightdm today, one core of my CPU is always maxed out
  at 100%.  I rolled back to version 1.2.3-0ubuntu2.5 and the issue
  stopped.  I tried this with 2 different kernels: 3.2.0-77-generic and
  3.2.0-79-generic and and version 1.2.3-0ubuntu2.6 of lightdm still
  caused 100% cpu usage.
