[Bug 1252121] Re: missing PrepareForSleep signal after resuming, causing networking to stay disabled

[Pablo180]

Spoke too soon, just hibernated and then resumed with Ethernet cable
plugged in and the problem occurred. Killing or restarting Network
Manager just caused nm-applet to crash so I had to restart that - which
is probably why the workaround no longer works.

I haven't noticed this problem in the week or so since the reinstall,
although I have been using wifi and not ethernet all that time - my wifi
was disabled via Network Manager before hibernating this time., so that
may be related.
