Comment 2 Radek Vykydal 2011-09-05 08:34:40 EDT
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.
Comment 3 Chris Lumens 2011-09-09 15:24:41 EDT
We certainly aren't going to support situations where NM doesn't run, but we still should display an error instead of just segfault.
Comment 4 Jan Stodola 2012-10-23 04:59:11 EDT
I haven't seen this error during testing of Fedora 18, so I'm closing this bug as resolved.
