Comment 126 for bug 105234

I've been experiencing this problem for many months in my two ubuntu desktops. In the beginning I had unmanaged devices in /etc/network/interfaces; however I deleted all the manually configured stuff there, and networkmanager applet is still broken. I have wireless, and it doesn't show up.

I'm wondering if there a way to safely "reset" /etc/network/interfaces (or whatever config files the applet is looking at)
