I don't have a simple recipe to preoduce the bug but it is simple enough
to understand.
While using the frameset--restore-frame function, it may happen that
the modify-frame-parameters be called with a border-width which
is not the default one for the current emacs. In this case,
x_set_border_width errors because it can't change it.
This happens if you restore a desktop which has been saved in another
environment. I don't think that an error is needed here. At most a
warning would be. Currently, it prevents restoring the desktop for
no real reason.

'border-width' is in ‘frameset--initial-params’ and should be filtered
appropriately. Can you provide a backtrace with a breakpoint in
if (FRAME_X_WINDOW (f) != 0)
error ("Cannot change the border width of a frame");

I have a simple way to reproduce the problem.

giving:
Error (frameset): Cannot change the border width of a frame
The frameset
I have not tried to reduce the frameset whatsoever.
My point is that the frameset is not compatible between my emacs-w64
session and my emacs-ubuntu session
because (at least) of the border-width which errors.
I was expecting to be able to run emacs independently on Windows and
GNU/Linux and being able to share
all of my setup. I get this error when the desktop package is restoring the
session.
Regards,
Fabrice

You earlier said that "it may happen that the modify-frame-parameters be
called with a border-width which is not the default one for the current
emacs. In this case, x_set_border_width errors because it can't change
it". ‘frameset-restore’ should process a ‘border-width’ parameter only
when _creating_ a frame. Note this remark in frameset.el:
;; - can be set at creation time, and setting them afterwards will fail with
;; an error, *unless* you set it to the same value, a noop (`border-width')
So I would need a Lisp backtrace from x_set_border_width to find out how
comes that ‘frameset-restore’ calls ‘modify-frame-parameters’ here.
Thanks, martin
