Title:
  Update impossible with update-manager -- loses connection to daemon

Status in “update-manager” package in Ubuntu:
  Confirmed

Bug description:
  When hitting 'Install Updates' on the Update Manager, it briefly greys
  out the manager but does not actually proceed to update anything.
  syslog says something has been queued:

  Nov 16 09:03:45 myserver AptDaemon: INFO: CommitPackages() was called: dbus.Array([dbus.String(u'')], signature=dbus.Signature('s')), dbus.Array([dbus.String(u'')], signature=dbus.Signature('s')), dbus.Array([dbus.String(u'')], signature=dbus.Signature('s')), dbus.Array([dbus.String(u'')], signature=dbus.Signature('s')), dbus.Array([dbus.String(u'icedtea-6-jre-cacao'), dbus.String(u'icedtea-6-jre-jamvm'), dbus.String(u'liblightdm-gobject-1-0'), dbus.String(u'openjdk-6-jre-headless'), dbus.String(u'openjdk-6-jre-lib')], signature=dbus.Signature('s')), dbus.Array([dbus.String(u'')], signature=dbus.Signature('s'))
  Nov 16 09:03:45 myserver AptDaemon.Trans: INFO: Queuing transaction /org/debian/apt/transaction/7d380769c12e48aa99632f955582f2f3

  after a while a window pops up informing me that
  "Task cannot be monitored or controlled"
  The connection to the daemon was lost. Most likely, the background daemon crashed.
  Details:
     It seems that the daemon died.

  Which is true since syslog tells us:

  Nov 16 09:06:04 myserver AptDaemon: INFO: Quitting due to inactivity
  Nov 16 09:06:04 myserver AptDaemon: INFO: Quitting was requested

  apt-get per commandline works fine as a workaround.
