Package: emacs
Version: 24.3
I ssh'd into a remote machine where I had a graphical session running.
Now:
emacs -Q -nw -l xesam
emacs -Q -nw -l tramp-gvfs
both fail to load the associated library with error message:
D-Bus error: "No connection to bus", :session
Debugger entered--Lisp error: (dbus-error "No connection to bus" :session)
dbus-get-unique-name(:session)
It ought to always be possible to load lisp libraries.

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xesam.el is obsolete (the XESAM interface is not used anymore by search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.

Not good enough: as Glenn wrote "It ought to always be possible to load
lisp libraries". They may be loaded for all kinds of reasons that have
nothing to do with using that library.

Feel free to do it (but even in obsolete/, it should be always possible
to load this library).

I understand this. However, there shall be an indication to the user
that all those (D-Bus based) Tramp methods are not available. How shall I
do it otherwise?
Well, maybe a warning. Would this be acceptable?

For sure. I'll move it.

Don't do it when loading the file, but instead do it when calling
its functions.
