I am having with the NetworkManger Applet 0.8.1 on Ubuntu 10.10 AMD64. It (or NetworkManager or my wireless driver) seem to crash occasionally, which means I lose all network connectivity. How can I debug NetworkManager and the applet on startup and login? I want to know what is causing the problem so that I can fix it or file a bug report.
Edit: This page provides some good details about debugging the NetworkManager daemon, but I'm still having trouble with the applet (e.g. the applet crashes, I lose my connection, I restart NetworkManager and use commandline utilities, regain my connection, but no applet comes back).
