No. I mean thats the only way I can see that behaviour.

Yes. That's what should happen.

This should be easy to debug if you instrument gdb-put-breakpoint-icon with
Edebug, click on the fringe to set a breakpoint, and step through the
function. The first gdb-put-string (anachronistic name) puts a bitmap in the
fringe (if reached), while put-image puts an image in the margin.
I've noticed that, in my case, although fringe-mode is nil, so that the
fringes should have the default width (8 pixels), (window-fringes) gives (10
11 nil). Just a guess, but if you are using a different toolkit (GTK?) perhaps
(window-fringes) gives something different again with a car of less than 8.
This is Kim's code so he can probably shed more light.
[Note for Kim: The doco for the variable fringe-mode mentions 'toggle-fringe'
but there doesn't appear to be any such function.]

I have seen something similar in an xterm but both-fringe-and-margins
mode shouldn't happen ordinarily. Lets debug one problem at a time.
