[Bug 1670177] [NEW] Cannot reconnect to my hidden network with plasma-nm on KUbuntu Trusty 14.04.5 LTS

Hi,

After my ISP home router is being rebooted, my KUbuntu Trusty 14.04.5
LTS does neighter reconnect to my hidden wifi network automatically nor
manually with the Plasma NM applet.

The ONLY workaround I have found so far is by typing the following
command :

$ nmcli con up id MyWifi

knowing that "MyWifi" is my hidden wifi connection name in the applet
(my "ESSID" is different)

Btw, I'm using kernel "4.4.0-64-generic" and "plasma-nm" version
"0.9.3.3-0ubuntu1" :

$ lsb_release -sd
Ubuntu 14.04.5 LTS
$ uname -r
4.4.0-64-generic
$ apt-cache policy plasma-nm
plasma-nm:
  Installed: 0.9.3.3-0ubuntu1
  Candidate: 0.9.3.3-0ubuntu1
  Version table:
 *** 0.9.3.3-0ubuntu1 0
        500 http://fr.archive.ubuntu.com/ubuntu/ trusty/universe amd64 Packages
        100 /var/lib/dpkg/status


Can you please have a look and try and fix this bug ?
