Dolphin create file .directory and network-manager stops working

Binary package hint: knetworkmanager

If you enter the Dolphin as root user (by sudo) in folder
"/etc/NetworkManager/system-connections/" and select "Show hidden files", so
create the file ".directory", within the same, after reboot, the
network-manager stop function and displaying the message in KnetworkManager "Networking
information not available" in knetwork-manager. If you remove the file and
restart, the problem becomes normal.

If necessary, I'll put the log Daemon.log here.
Thanks and hope to have helped
