升级到Debian Jessie和gnome 3.14.1后gnome控制中心出现问题

我最近将我的Debian系统升级为Jessie/stable（其中还包括对Gnome 3.14.1的更新）。从那以后，当我跑步的时候

gnome-control-center network

，我得到以下错误：

(gnome-control-center:9451): GLib-CRITICAL **: g_variant_get_type: assertion 'value != NULL' failed

(gnome-control-center:9451): GLib-CRITICAL **: g_variant_type_is_subtype_of: assertion 'g_variant_type_check (type)' failed

(gnome-control-center:9451): GLib-CRITICAL **: g_variant_get_boolean: assertion 'g_variant_is_of_type (value, G_VARIANT_TYPE_BOOLEAN)' failed

(gnome-control-center:9451): GLib-CRITICAL **: g_variant_get_boolean: assertion 'g_variant_is_of_type (value, G_VARIANT_TYPE_BOOLEAN)' failed

此外，control center窗口中显示的网络信息（IP/DNS/…）与实际设置不同，但实际设置仍然有效

除此之外，我还得到了类似的输出

gnome-control-center sharing

:

在这里，所有共享选项都被禁用。而我不能让他们

有什么建议可能导致这种行为
