Bug Description

After a few months without issue, the Network Manager applet has suddenly disappeared from the tray not long after booting into Ubuntu. I am filing this bug report based upon the instructions provided for bug #43379.

Sorry. Got the readings backwards. Braincramp moment. Should I file a separate bug report?

No, it is fine now. You might be able to get any more hints about what happens if you kill it and start it from the command line and see if it outputs something before it crashes.

Thanks for the hint. Here's what the terminal says upon nm-applet running and then crashing a few hours later.

$ nm-applet
** Message: applet now removed from the notification area
** Message: PID 14679 (we are 10421) sent signal 15, shutting down...

Strange. Seems like it's something killing it.

Is there a way to trace which process was tied to the PID?
