If this bug refers to the inelegant and tedious behavior in which LTSP clients have to click Shutdown 3 times (once on the desktop, again in a Shutdown/Restart dialog, and the dropping back to the login screen, choose Preferences: Shutdown), then I confirm that it is still a problem under Ubuntu 12.04.
