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