Hi all,
I'm also affected and wanted to contribute my NetworkManager output.
As I cannot run the above gdb command, because I don't know how to connect to
my wifi without nm-applet(which is not working when NetworkManager is started
by gdb) I will provide the output of sudo /usr/sbin/NetworkManager --no-daemon
--log-level=debug.

Title:
network-manager segfaulting after bringing up Wi-Fi link
Status in “network-manager” package in Ubuntu:
Incomplete
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[7265]: segfault at 0 ip 7f03d9939f7d sp
7fff1f62cbb0 error 4 in libc-2.15.so[7f03d9833000+1b3000]
[ 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,

(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.
