Comment 3 for bug 1155388

Disabling IPv6 worked for me, but it also works if you just tell Network Manager to not require IPv6 to complete for the connection to stay up. For some reason Network Manager is segfaulting when these steps are not taken. Oddly enough, it worked out of the box on my netbook. I cannot re-create the problem on my netbook, it works just fine when I have that box checked and IPv6 set to Automatic.
