Bug Description

I'm connected via a bluetooth modem, and I put the modem off the bluetooth range, so the connection died.
Apport come up with a window crash. When I go in the nm applet menu in order to reconnect, the name of the connection was replaced by "EmptyLabel", but a click on it, restabilished the connection fine.

A further trying to reproduce the bug didn't end well: the apport window didn't come up.
