Binary package hint: network-manager

Current NetworkManager in karmic reliably crashes when my 802.11g AP drops the connection.

DistroRelease: Ubuntu 9.10
ExecutablePath: /usr/sbin/NetworkManager
Gconf: Failure listing entries in `/system/networking': Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See http://projects.gnome.org/gconf/ for information. (Details - 1: Failed to get connection to session: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken.)

Great, apport's marked my bug as a duplicate of a bug I'm not permitted to see :-(
