I've run these tests (and I kept the buggy frame emacs around while I
did so and I still have it, would attaching gdb to it give you anything
useful?) in this case the frame was displaying neither the decorations
nor the minibuffer

In all 4 cases I'm afraid the bug did *not* appear - I assume this is
what I was meant to look for with just a visual check. I also compared the
emacs frame with the buggy one (maybe you already realise this) and by
aligning the top of the menubar in each frame the buggy frame stops
just at the point where the buffer modeline should appear, looking
carefully I can just see the tops of the characters on the next line
of WikipediaApplet.cpp

Maybe I should add that in all cases (since I first saw the bug) I've
been running emacs from its build directory - so for me ~/emacs-bzr/src/emacs
(rather than installing it in /usr/local/bin)

I had the following lines at the head of bug17046.el

(sit-for 0) ;; commented out as required
