I have the same problem. It seems that it only appears when the network
interface receives an IPv6 address.
"sudo service network-manager restart" helps slightly, but not completely.

...and so on.
After restarting NetworkManager is no longer occupies 50-100% CPU, but still
not 0.

Title:
NM gobbles CPU and reports repeatedly to .xsession-errors: 'Could not
create object for /org/freedesktop/NetworkManager/IP6Config/<nnnn>:
Method "GetAll" ... doesn't exist'
Status in “network-manager” package in Ubuntu:
Incomplete
Bug description:
NetworkManager consumes lots of cpu and reports this to .xsession-
erros again and again:
Could not create object for
/org/freedesktop/NetworkManager/IP6Config/3628: Method "GetAll" with
signature "s" on interface "org.freedesktop.DBus.Properties" doesn't
exist
This happens on a desktop connected via ethernet and a laptop connected via
wireless (ipv6 is enabled on the network)
On both computers NetworkManager consumes 100% cpu.
Both run up to date Ubuntu 12.04, Laptop was upgraded, Desktop newly instaled
from beta2 image.
