I've wrapped the call of `dbus-get-unique-name' by
`ignore-errors'. tramp-gvfs.el returns now the user error "Package
`tramp-gvfs' not supported", which is intended.

xesam.el is obsolete (the XESAM interface is not used anymore by search
engines). Shouldn't we move xesam.el to "obsolete/"?

Best regards, Michael.
