Unfortunately, the stack trace appears to be unusable. That said, we've
done some changes lately to NetworkManager and nm-applet and I think
they probably fix this crash. Can you make sure your system is fully up
to date and then test again to see if you can still reproduce this
issue?

Title:
nm-applet crashed with SIGSEGV in quark_strdup()
Status in “network-manager-applet” package in Ubuntu:
Incomplete
Bug description:
This occurred with a
Network controller: Broadcom Corporation BCM43224 802.11a/b/g/n (rev 01)
as my wireless card. Ubuntu 12.04 still cannot detect wireless networks with
this card, so I thought I'd try connecting to a hidden wireless network. Every
time I try to connect to a hidden wireless network, I get this SIGSEGV. The
laptop is a Lenovo E420 ThinkPad.
