NM connection editor: Adding wired connections does not work

Bug Description

Binary package hint: network-manager

after booting one time the Network Connections list was suddenly empty. (and thus no network connection)
using ifconfig eth0 is there but was not up.

starting the network-manager and trying to add a wired connection does nothing for the first time you press the 'add' button. on the command line is gives the following error message:

(nm-connection-editor:4923): GLib-CRITICAL **: g_hash_table_lookup: assertion `hash_table != NULL' failed

** (nm-connection-editor:4923): WARNING **: Unknown setting '802-3-ethernet'

** (nm-connection-editor:4923): WARNING **: create_new_connection_for_type: unhandled connection type '(null)'

** (nm-connection-editor:4923): WARNING **: Can't add new connection of type '802-3-ethernet'

pressing the button a second time yields the editing-wired-connection-1 dialog.
trying to add the 'new' connection with the 'Available to all users' option enabled gave me the following error message:

Could not add connection - PolicyKit authorization could not be created; invalid action ID
[WARN 4923] polkit-action.c:211:polkit_action_set_action_id(): polkit_action_validate_id (action_id)

I'm also experiencing this.

I.e. if one NIC (whether wired or wireless) is declared as static /etc/network/interfaces,
then I can't create a *system* connection with nm-connection-editor for the other NIC.

I'm able to create user connections, i.e. without checking the "Available to all users" checkbox,
but if I try to check this box and make them system connections later on,
then the connections disappear from nm-connection-editor.

In all cases, even if they don't show up in the nm-connection-editor dialog, the connections *are present* on the file system, I can see them in /etc/NetworkManager/system-connections.

If I remove the static NIC declaration from /etc/network/interfaces everything works fine.

I have the same problem, I would like to use interfaces file with wpa_supplicant at system startup (for always connected / user session connection independance ) and also I need a second wired connection shared with other computers at system level, so I configureg a static wireless network in /etc/network/interafaces and tried to use nm-connection-editor to add a shared connection on the second eth wired but connection disappeared, only the file is present in the etc dir . I'd like to do it with network manager before using dhcpd way cause my users are "dummy"
