Hi,

Once ses is loaded I am getting the following error on kill in magit buffers:

Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)
  ses--advice-copy-region-as-kill(#[770 "\
  apply(ses--advice-copy-region-as-kill #[770 
  copy-region-as-kill(nil nil region)
  magit-copy-buffer-revision()
  funcall-interactively(magit-copy-buffer-revision)
  #<subr call-interactively>(magit-copy-buffer-revision nil nil)
  apply(#<subr call-interactively> magit-copy-buffer-revision (nil nil))
  call-interactively@ido-cr+-record-current-command(#<subr call-interactively> magit-copy-buffer-revision nil nil)
  apply(call-interactively@ido-cr+-record-current-command #<subr call-interactively> (magit-copy-buffer-revision nil nil))
  call-interactively(magit-copy-buffer-revision nil nil)
  command-execute(magit-copy-buffer-revision)


Magit calls (copy-region-as-kill nil nil 'region). According to the doc first
two args should be ignored when 'region is passed. So I would assume it's the
bug in `ses--advice-copy-region-as-kill` then.


Thanks,

  Vitalie

Thank you for the report.
I've noticed that `copy-region-as-kill' also needs `natnump' checks for
BEG, END.
How about th following patch?
