I see the same call to 'yank' in both clipboard-yank and
x-clipboard-yank, so I'm not sure I understand what difference in
behavior you see (you also didn't say which version of Emacs did you
use).  Can you show a reproducible recipe starting from "emacs -Q"
which could be used to see the problem?

Thanks.
