[Bug 1418310] [NEW] Network manager loses network devices

 

Public bug reported:

The network manager icon will indicate that it's not connected to a wireless network, and when I click on the indicator, it displays the message "no network devices available".
I cannot reliably recreate this, but it's definitely a bug since I'm filling this report while it's occuring.
