OK. This master,


http://git.savannah.gnu.org/cgit/emacs.git/snapshot/emacs-7ac84a2570e1268cc040fcd529508307b2b22c01.tar.gz

(http://git.savannah.gnu.org/cgit/emacs.git/commit/?id=7ac84a2570e1268cc040fcd529508307b2b22c01)

works as expected.

Instead the next,


http://git.savannah.gnu.org/cgit/emacs.git/snapshot/emacs-ee14727ce033bae3bc11af35e7843604e5a5e635.tar.gz

(http://git.savannah.gnu.org/cgit/emacs.git/commit/?id=ee14727ce033bae3bc11af35e7843604e5a5e635)

shows the tooltip garbage I described.

For what I can see, the issue regards only the GTK build on GNU/Linux 
(Linux Mint 17.1 64 bit, with GTK+ 3.10)

Ciao,
 Angelo.
