Bug description:
Hello,
On Ubuntu 15.10 4.2.0-35, with network-manager 1.0.4-0ubuntu5.3
My WiFi connection is very unstable and I have to often restart
NetworkManager service (~ a dozen times every day...):
sudo systemctl -l status NetworkManager

Also, each time I restart my desktop, NetworkManager generates a crash
report: cf. attached screenshots.
I have tried an Ubuntu VM with the same packages related to networking and
the exact same releases (same repositories), the crash never happens; the
difference appears to be only the type of network connection: WiFi for the
desktop vs Ethernet for the VM.
Any suggestion?
