Actually, what I think it indicates is that the Gtk team have for a long
time had a sense of good default values for tooltip timeout and tooltip
browse timeout which don't suit the more complex programs such as gimp.
(I'm guessing here that gimp is using the default values); indeed as I
move down the menus in gimp unless they are broken up by non-tooltip
items the tooltips once started are difficult to shake off. 

I strongly suspect that is why I looked up the API and gave the user
control in Denemo. All that has happened in Gtk 3.10 is that the user no
longer gets control. Looking at other applications that my (old -
Wheezy) Debian distro provides I see that most do not have tooltips,
Evince in particular is at version 3.4.0 and has no tooltips and
Evolution 3.4.4 has none either.

Thanks for the link, it is often difficult to track down the place to
raise an issue.
