From Emacs -Q configured with --with-ns, kill some text (e.g. from the
*scratch* buffer) and then try and paste it into another program.
Notice that it hasn't been copied.  This works on the emacs-24 branch.

I tried tracking it down and it seems to be due to STRINGP (data)
failing on line 369 of src/nsselect.m.  I didn't try debugging further
to see _why_ it was failing.  I also did not try bisecting it, but I can
do that if desired.

Thanks,
Ivan
