Comment 168 for bug 1252121

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.
