gnome-power-manager hibernates laptop on ac cable removal

[dennis]

Laptop: Sony VAIO-FS790, perfect battery
Ubuntu: Dapper Drake - fully up to date
gpm : Version 2.14.3

reproducing:
After a recent upgrade to gpm 2.14.3, unplugging the ac cable sends my laptop into hibernate. I have managed to reproduce this without fail - even after a fresh reboot. This still happens with a full battery. A critical battery warning preceeds the hibernate. Please let me know what log files to report. Thanks

gnome-power-manager (2.14.3-0ubuntu2) dapper; urgency=low

  * Patches added in this version:
    - 20-enable-xfce-startup.patch
      Enable XFCE in the .desktop file so that it starts up for xubuntu too.
      Closes: launchpad #43077
    - 30-transparent-notification-icon.patch
      Enable the eggtrayicon stuff to do transparency.
      Closes: launchpad #40446
    - 95-lid-state-tracking.patch
      Augment lid state tracking to use hal if hal reports it is capable
      of tracking the lid state.
      If hal reports an acpi_LID with button.has_state == true then we use
      that state information whenever we want to consider the lid switch
      This should deal with LP #33072 and thus its duplicates #42988,
      #42823, #40730, #40662, #37442, #36459 and #33952
    - 96-disable-session-save-on-shutdown.patch
      Disable the saving of the session during critical power shutdown.
      This confuses too many people for now.
      Closes: launchpad #35691
  * Patches changed in this version:
    - 40-ubuntu-schema-defaults.patch
      Alter screen lock defaults to always lock, regardless of screensaver.
      Closes: launchpad #39448
  * Related fixes: #35591 -- We believe this is caused by the hal and
    gnome-power-manager interaction wrt. lid status. The new hal and the
    2.14.3 gnome-power-manager should fix it all.
