Please file a bug report on launchpad.

It's probably a chance to make an example of scripting in guile for
gschem.

Put the following code into your gschemrc:

--------------------8<----------------------
  (use-modules (geda page))
  (use-modules (gschem selection))
  (use-modules (gschem hook))

  (define copied-objects '())

  (define (get-copied-objects)
    copied-objects)

  (define (set-copied-objects! ls)
    (set! copied-objects ls))

  (define my-selection-hook (make-hook))

  (add-hook! my-selection-hook
    (lambda ()
      (for-each select-object! (get-copied-objects))))

  (add-hook! copy-objects-hook
    (lambda (ls)
      (begin 
        (for-each deselect-object! (page-selection (active-page)))
        (set-copied-objects! ls))))

  (add-hook! paste-objects-hook
    (lambda (ls)
      (run-hook my-selection-hook)))
-------------------->8----------------------

or into, say, ~/.gEDA/myselection.scm
and put into gschemrc just
  (load "myselection.scm")

This code is for selecting only copied objects. If you want select all
pasted objects (even if you paste them using shortcut) it would even be
simpler.

It works in gschem 1.9.1 with guile 2.0, but probably will work with
other combinations as well.

If anybody is interested how all this works, I could make clear some
details.

Cheers,
  Vladimir
