Bug Description

Cannot use panel interface to add wireless connection

* on fresh install of Lubuntu Next 17.10 Beta1 i386 (build 20170831)
* complete the installation and reboot into new OS
* Use Panel Applet to view Network Connections or execute command:

nm-connection-editor

* Choose the connection for the wireless access point you wish to connect to
* click edit

- Connection Editor window simply disappears
- command line reports "segmentation fault"
- see attached dmesg for details (nm-connection-e segfault error 4 in libnma.so.0.0.0)

This prevents the user from adding a wireless connection through the GUI.

WORKAROUND: nmcli -ask con up MYSSID

example:

# check device is active
nmcli dev
# look for connections
nmcli con

# enter PSK where MYSSID is the connection name from above
nmcli -ask con up MYSSID

# Now recheck wireless
nmcli con
nmcli dev
# check IP address is configured
ip addr
# test connection
ping 8.8.8.8
nslookup ubuntu.com
