nm-applet goes unresponsive randomly

[Mikko Rauhala]

nm-applet sometimes goes unresponsive, generally after a couple of days of intermittent laptop use (including suspends). The menu does come up, but choosing an interface to activate doesn't do anything for either wifi or mobile networks. Not even a visible attempt is made to connect, nor is a failure reported.

Killing nm-applet and restarting it is a functional workaround (and thus is also logging out and back in), so it's clearly the applet and not network manager itself that's the problem. While there is a workaround, this is likely to be very frustrating for users, especially those less likely to come up with the kill/restart workaround.

Using the standard Unity interface, if that matters.

This is very likely a duplicate of bug 930563.
