We need the icon to have a name.

Looks like the icon doesn't have a name.

Yup.

Hard to say without looking at it. Could be an Accerciser thing. Failing
that, here's my theory (based on experience with similar situations):
Some Gtk+ widget -- which does not have a corresponding accessible
object representing itself to us -- becomes focused. That's resulting in
corresponding accessible events. Those events are, in turn, resulting in
the creation of an accessible object. And the object which is being
created lacks a name.

Not possible AFAIK.

I would prefer that the icon be named correctly, because if you get that
icon a name, Orca should automatically present it as you expect. :-)

Given that the programmer has gone to the trouble of assigning the icon
a title for screen readers, what I'd be investigating are:

1. Does title mean accessible name, or does it mean something else (like
accessible object description or accessible image description)?

2. What widget has this title?

3. What widget is claiming focus?

4. Is the widget from question 2 the same widget as the one from
question 3? (i.e. and not a child or ancestor)

HTH.
