When I start emacs, I get errors like:

(emacs:13939): GLib-GObject-WARNING **: IA__g_object_notify: object class
`GtkMenuItem' has no property named `label'

They appear periodically as I do various things in Emacs. The first
one appears before doing anything at all. I do not witness these
warnings using Emacs 24.3.

This is with recent trunk revision a693e5b566a7a88fecbb95b1f64426c9f52b3198.

GtkMenuItem's "label" property was introduced in GTK+ 2.16, according to 
<https://bugreports.qt-project.org/browse/QTBUG-8537>. You're using GTK+ 
2.10.4, which could explain the problem. I'm using Firefox 20 which has 
GTK+ 3.10.6 and do not see the problem.

I suspect that the attached patch (which is trunk bzr 115967.1.1) is 
what introduced the problem. If you back this change out, does it fix 
things? I'll CC: this to Daniel Colascione to give him a heads-up.

Confirmed: reversing the patch on today's trunk causes the error message to
disappear.

I added the obvious gtk version check.

Thanks.
Note this issue is in emacs-24 branch too. Does it matter, or is it just
a warning?

It is just a warning.  g_object_notify returns without doing anything or any harm.
