sysinfo crashes when selecting the System tab with Exception in Gtk# callback delegate

[Eyad Salah]

Binary package hint: sysinfo

I start sysinfo and it works fine unless I select the "system" tab then it crashes with the following output:

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

  Note: Applications can use GLib.ExceptionManager.UnhandledException to handle the exception.

Same in 11.04 (which is at a very early state, admittedly)
