[Xfce4-commits] [xfce/xfconf] 05/31: Port xfconf_channel_get_arrayv to gdbus. Now the function works as follows: xfconf_channel_get_internal is called to get a GValue which should contain a GVariant that is an array of variants value. Each of these GVariant value is transformed to a GValue and added to the GPtrArray.

    Port xfconf_channel_get_arrayv to gdbus. Now the function works
    as follows: xfconf_channel_get_internal is called to get a GValue
    which should contain a GVariant that is an array of variants value.
    Each of these GVariant value is transformed to a GValue and added
    to the GPtrArray.
