0.8.2: nm-connection-edit does not ask for authorization on system connections

[Andrey Borzenkov <arvidjaar gmail com>]

Trying to use nm-connection-editor under KDE (it is SVN snapshot
4.5.76) to edit system connection results only in "Insufficient
privileges". I am not asked for authentication.

The only output from n-c-e is

{pts/0}% nm-connection-editor

(nm-connection-editor:23585): Gtk-WARNING **: GtkSpinButton: setting
an adjustment with non-zero page size is deprecated

(nm-connection-editor:23585): Gtk-WARNING **: GtkSpinButton: setting
an adjustment with non-zero page size is deprecated

(nm-connection-editor:23585): Gtk-WARNING **: GtkSpinButton: setting

(nm-connection-editor:23585): Gtk-WARNING **: GtkSpinButton: setting
an adjustment with non-zero page size is deprecated

** (nm-connection-editor:23585): WARNING **: dispose: CEPolkitButton
object 0x14f6b40 disposed twice


This definitely worked in the past with earlier NM/KDE versions.

Just asking for debugging tips, in the first place - any possibility
to get log of ehat exactly happens (i.e. - n-c-e does not make any
request, NM does not make any request, ...)

TIA
