Hi. I noticed the output from sysinfo is identical to the output posted
in bug 596727. I am unsure if the first error ("Error
org.freedesktop.org.DBus.Error.Spawn.ChildExited: Launchelper exited
with unknown returncode 1") is related to this, though.

Title:
  sysinfo closes with unknown dbus-error

Status in “sysinfo” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: dbus

  since yesterday at about 23:30 CET, I got this error-message in the
  Terminal:

  Error org.freedesktop.org.DBus.Error.Spawn.ChildExited: Launchelper
  exited with unknown returncode 1

  This continues since then through all upgrades since this time.

  Then I found out, that this bug seems to have something to do with
  sysinfo. Because as soon as I start this programm and klick on the
  first point where it sys "system", the program closes and gives the
  following Output in the Terminal:

  GConf.NoSuchKeyException: Key '/apps/sysinfo/window_width' not found in GConf
    at GConf.Client.Get (System.String key) [0x00000] in <filename unknown>:0

  Exception in Gtk# callback delegate
    Note: Applications can use GLib.ExceptionManager.UnhandledException to handle the exception.

     at Sysinfo.Sysinfo..ctor(System.String[] args)
     at Sysinfo.Sysinfo.Main(System.String[] args)

  Then I checked the other programs installed, but couldn't discover any
  other thing, so I can say, that the system itself runs normal and also
  do the other programs installed.

  So my questions would be:
  where does the above mentioned Error-message come from and is it necessary to act in any way or is it necessary to do anything??

  Then I want to add some information about my system:

  System: Maverick Meerkat (Ubuntu 10.10)
  Kernel: 2.6.35-14-generic
  Desktop: Gnome 2.31.6
  architecture: x86_64
