You can remove your device's number from /usr/pluto/locks/pluto_spawned_local_devices.txt and reload router to get it to return as well. Make sure it is not 'disabled' in webadmin.
The pastebin's show more info than we've seen yet. The segault is new. I'm afraid this may not be easy to track down. I'm going to try running some GSD stuff in a debugger to see if anything other info pops out. Not sure when I'll get to that yet.
