I don't know about the default handler, but if it's a firefox bug it's too late to fix it now (if at all) for dapper, and it may be used by other apps too.
if it's a GNOME private thing it should not be used by non-gnome apps. If they use it and rely on it there may be no other way for apps other than nautilus to play nice with them. And if x-directory/gnome-default-handle is a fallback for when no x-directory is listed why it is used? AFAIk there are two such handlers listed in our case one for nautilus one for thunar? -- Gnome's Places menu starts Konqueror instead of Nautilus https://launchpad.net/bugs/35997 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
