When a FolderIcon is opened, it asks the parent view to allocate space for it, which takes time. Eventually, the space-ready signal is emitted on the view and the icon can make use of the new space with its popup. If the icon gets destroyed in the interim, though, space-ready signal handler still fires. This commit disconnects the signal handler so it doesn't get called on a destroyed icon. https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/628
