Certainly. This is after installing network-manager-gnome-dbgsym,
libnma0-dbgsym, and libgtk-3-0-dbgsym:

After installing libgtk-3-0-dbgsym, it's now freezing in gdb instead of
crashing. I don't know if this is coincidental or not. This is the
backtrace before installing libgtk-3-0-dbgsym, where the network manager
applet completely crashes/vanishes, instead of merely freezing:

Also, after poking around a bit, I've noticed this only occurs when
trying to add a WPA network, not when connecting to a pre-established
WPA network. I.e. if network-foo was already known by network-manager
before I upgrade network-manager-gnome to 1.8.2, I can still connect and
disconnect without a segfault. It's only when attempting to add the
network that I have the trouble.

Cheers!
