[Bug 737615] Re: Can't save changes in "Edit Connections..." for Wi-Fi networks to which one doesn't have the password

The problem is in the settings of the connection, but unfortunates the
manager does not display this information.


SOLUTION:
- start nm-connection-editor from the terminal (sudo is possible, bus probably not necessary). 
- open the connection settings as usual in the popped-up manager
- The exact error message will be printed in the terminal, read it. 
- Fix the error and the buttons will be available again.


EXAMPLE OUTPUT in the terminal (in German in my case and I had to mark
Certificate as ignored ):

** Message: Cannot save connection due to error: Editors wird initialisiert …
** Message: Cannot save connection due to error: ungültige Einstellung Sicherheit des Funknetzwerks: Ungültiges EAP-PEAP-CA-Zertifikat: Kein Zertifikat angegeben
** Message: Cannot save connection due to error: ungültige Einstellung IPv4-Einstellungen: ipv4.addresses: Diese Eigenschaft darf nicht für »method=manual« leer sein
