When I was editting some files on a server through a ssh connection I added the dir I was working in to the "save as" side bar. This directory turned up in Ubuntu Hoary's new "Places" menu as well, and after that secretly drove me crazy. Everytime I logged in, everytime Nautilus started, it asked me to log in to the server. I couldn't figure out for a while what was causing it, until I saw that directory there. Then I couldn't figure out how to remove it from the "Places" menu. It was no longer in my "save" dialog. After googling for some time I found it was the .gtk_bookmarks file in my home dir that contained this info (and only that one, not the "Home" and the server connections and such). I removed the line, saved the file (gnome panel crashed) and voila, no more password buggings!
