Title:
  GDM logs out after some minutes of typing on the keyboard

Status in “util-linux” package in Ubuntu:

Status in “gdm” source package in Karmic:

Status in “util-linux” source package in Karmic:

Bug description:
  Using Ubuntu Karmic x86_64, as of 06.07.09. Possibly relevant package:
  gdm: Installed: 2.26.1-0ubuntu3

  Problem:
  After logging in via gdm (system freshly started up), after some minutes of typing (no matter in which program), I suddenly, without any warning, get kicked out of my session and back to the login screen. I suspect that this "event" is triggered by an unlucky but likely to occur key sequence. If I do not type anything the issue does not occur. There does not seem to be any single trigger key (i.e. the last key pressed before I get kicked out is not always the same one).
  After re-logging back in, the issue does not occur anymore, until the next reboot.

  Likely related symptoms:
  - The first gdm session appears to start on tty1, the ones after the crash on tty7
  - After the crash, if I switch to tty1, many random characters are printed, i.e.

  $HOSTNAME login: *88;888;8;8<88A8
  Ubuntu karmic (development branch) $HOSTNAME tty1

  $HOSTNAME login: *1
  Ubuntu karmic (development branch) $HOSTNAME tty1

  [...]

  $HOSTNAME login: 5.........215,1$9 1& 9 9!&SSSSS09!&,1/GHG.//79.1 4  *1"*2.99*1&,99*2*9*29*!9*24''''''*KKKKKKKKKKKKKKKKKKKKKKK.03KM/**********************
                                                                                         Pa
  ssword:
  Ubuntu karmic (development branch) $HOSTNAME tty1

  $HOSTNAME login:
  Ubuntu karmic (development branch) $HOSTNAME tty1

  - GDM seemes to crash (it actually looks more like a controlled logout) when tty1 displays "password:"
  - The above random characters have little to do with the ones I pressed.
  - No related errors are to be found in any system log (which is why I suspect it is a controlled logout rather than a crash)
