bug#6680: 24.0.50; yank (paste) on os x

[rick frankel <rick@rickster.com>]

Copy (M-W)/Yank (C-Y) causes the error:

     Quit: "pasteboard doesn't contain valid data"

since the integration (revno: 100824 [merge]) of 2010-07-15. 

Note that the nightly of 2010-07-14 works, and that kill (C-K).../Yank
works as well.

      1) $ ./nextstep/Emacs.app/Contents/MacOS/Emacs -Q
      2) Select default text in '*scratch*' buffer.
      3) M-W (Copy)
      4) C-Y (Yank)
