NetworkManager crashed with SIGSEGV in nm_dhcp_client_start_ip6()

[Effigy]

Ubuntu 11.10 64bit
Laptop Aspire 4830TG-6450

Problem happens when opening laptop lid to resume from sleep -> entering password -> resuming desktop.
Network starts to resume but issues error about crashing, then after a few seconds it resumes as normal.
Also noticed network does not remember the last used network and tries connecting to neighbors sometimes.
I could just ignore this type of error but I though better handeling of the network after resuming connection would be a better choice.

Let me know if any more info is needed.
Thanks in advance.
