Public bug reported:

First, my usual network disappeared from the list, and I had to connect
to another. It worked great, but I needed to communicate with a machine
on the old network, so I replugged my USB WLAN adapter, and I could
connect again. A few minutes later, network-manager crashed. The
connection still works though.

This seems to be the problem:
