I get xfsettingsd core dumps:

Core was generated by `xfsettingsd'.
Program terminated with signal SIGSEGV, Segmentation fault.

so a NULL deref.

 Here are details with debug info:

 Core was generated by `xfsettingsd'.
 Program terminated with signal SIGSEGV, Segmentation fault.
 #0  0x0000000042a15e74 in up_exported_daemon_get_lid_is_closed (object=0x0)
     at up-daemon-generated.c:747
 747       return UP_EXPORTED_DAEMON_GET_IFACE (object)->get_lid_is_closed (object);

 This seems to be called from:

 gboolean
 up_client_get_lid_is_closed (UpClient *client)
 {
         g_return_val_if_fail (UP_IS_CLIENT (client), FALSE);
         return up_exported_daemon_get_lid_is_closed (client->priv->proxy);
 }

 and when running xfsettingsd manually:

  > xfsettingsd --replace
  >

 (xfsettingsd:233): xfsettingsd-WARNING **: 08:21:48.919: Property "/Gdk/WindowScalingFactor" has an unsupported type "guint".

 (xfsettingsd:233): libupower-glib-WARNING **: 08:21:49.808: Couldn't connect to proxy: Could not connect: No such file or directory


 Now this is a desktop machine and it has no lid - but I guess this is all
 lost somewhere in the stupid dbus magic behind this.

 This patch seems to help, and it makes the "Appearance" applet work a bit
 better.

 Is this the same as 53455?

I recently committed a patch to sysutils/upower.
Could you test if the problem still occurs when using the new version?

 Martin: does xfsettingsd still crash for you?
