Yep, the SIGSEGV seems like a consequence of NM not being activated (bug #733680). I am keeping this one open to consider whether we want to handle this situation more gracefuly than with sigsegv, but not being able to start NM is pretty fatal fail so I don't give much priority to chasing the sigsegv cause now.
We certainly aren't going to support situations where NM doesn't run, but we still should display an error instead of just segfault.
I haven't seen this error during testing of Fedora 18, so I'm closing this bug as resolved.
