No, it's a dupe of 802271.

I think this has more to do with the keyboard being in the wrong mode than
there being something else listening at the time - the wrong mode being a
sign that more than one process is trying to use the VT and they have
different opinions about what mode the keyboard should be in.  So this is a
VT allocation bug - in this case one in lightdm.

Title:
  Xorg crashed with SIGQUIT

Status in “lightdm” package in Ubuntu:
  New

Bug description:
  Ubuntu: 11.10 Oneiric
  xorg-server: 1:7.6+7ubuntu1

  Caught a crash when hit "enter" key at some time after launch. Dropped
  to console showing login prompt and looks like some garbage were
  entered for username. That VTY was inoperable, had to switch to
  another one and restart lightdm.

  Found this in /var/log/Xorg.0.log:
