[SOLVED] NetworkManager dumped core
Symptoms: WiFi randomly drops out.
More specifically: NetworkManager core dumps and network-manager-applet stops (Gnome 3.8)
If anyone has suggestions, I'd be grateful. I'm at a loss, other than disabling NetworkManager and enabling netctl. Details follow below.
Thanks so much!

I'm marking this topic SOLVED, though more accurately, I should say that I've worked around the problem.
I achieved a stable wireless connection by changing APs, which leads me to believe that the underlying problem is upstream. Specifically, the problem is most likely that NetworkManager is not compatible with all APs. In my case, when I connect to a Netgear NDR3700v1 running dd-wrt, NetworkManager and nn-applet crashed randomly and frequently. However, after changing to an Apple Airport AP, I achieved a stable connection without crashes.
Bottomline: if you experience wireless connection troubles with NetworkManager and nm-applet, the problem may be that NetworkManager is not "compatible" with your AP hardware.
