Better yet, could you try this patch instead?

Title:
  ltsp: screen session "ssh" not working in precise

Status in “ltsp” package in Ubuntu:
  New

Bug description:
  We have "SCREEN_02=ssh" in our lts.conf. It used to work properly, but
  since update to precise, it fails.

  What happens:
  - Press ALT+F2
  - promt "Username:" is shown on top of the screen
  - enter user name, press ENTER
  - a message on ssh usage is shown on the screen, indicating that ssh was called with wrong parameters
  - after a few seconds, screen is cleared and reads "Username:" again

  
  What should happen:
  - Press ALT+F2
  - prompt "Username:" is shown on top of the screen
  - enter user name, press ENTER
  - script prompts password
  - script starts ssh session to LTSP server

  Note: The usage message seems to indicate that the environment
  variable "SERVER" is not known to the ssh screen script. Is this
  variable known when the ssh script ist called?
