Bug Description
On my system after updating today, I see network manager bring up my wifi link and then immediately start reconnecting.
In my dmesg, I see many sequences of messages like
[ 2027.559748] NetworkManager[
[ 2027.561881] init: network-manager main process (7265) killed by SEGV signal
[ 2027.561942] init: network-manager main process ended, respawning
my /var/log/apport.log shows
ERROR: apport (pid 7120) Mon Jul 16 18:50:02 2012: called for pid 6970, signal 11, core limit 0
ERROR: apport (pid 7120) Mon Jul 16 18:50:02 2012: executable: /usr/sbin/
ERROR: apport (pid 7120) Mon Jul 16 18:50:02 2012: is_closing_
ERROR: apport (pid 7120) Mon Jul 16 18:50:02 2012: this executable already crashed 2 times, ignoring
(I lost some reports because of course apport fails to upload while the network is down)
Not sure what's going on, but I do note that there is a new network-manager version as of today.

I am running the same version of n-m with both wired and Wi-Fi connections and don't get a segfault.
The segfault occurs after an IPv6-related message. Does the segfault go away if you disable IPv6?
