Looking in the syslog you posted, this:

Mar 13 11:31:39 candy kernel: [ 2202.908747] type=1503 audit(1236943899.825:13): operation="inode_permission" requested_mask="w::" denied_mask="w::" fsuid=0 name="/var/run/dbus/system_bus_socket" pid=7934 profile="/usr/lib/NetworkManager/nm-dhcp-client.action"

looks to be the probable source of the issue. Adding the line

  /var/run/dbus/system_bus_socket w,

to the /usr/lib/NetworkManager/nm-dhcp-client.action section of
/usr/lib/NetworkManager/nm-dhcp-client.action and reload the apparmor
policy by restarting the apparmor initscript should address it.

Thanks.
