In daemon/gvfsbackendcomputer.c around line 522 we have
file->display_name = g_strdup (_("Filesystem"));
file->icon = g_themed_icon_new ("drive-harddisk");
file->root = g_file_new_for_path ("/");
I think just changing "drive-harddisk" to "drive-harddisk-dist" and providing an icon would do it.
Actually this is not a nautilus bug, it's gvfs.
