Comment 23 for bug 37128

I just installed herd 2, and installed network manager and updated at the same time. I had the same problem

"gtk-update-icon-cache -f /usr/share/icons/hicolor/" fixed the issue.

this bug has been in since dapper and certainly hope it gets fixed by the time feisty comes out (or even better would be to have network manager installed by default. I still don't understand why Ubuntu is behind almost every other distro in this sense)
