I think there's not currently a way to set the icon for a dialog.

Possibly, this was never supported because a dialog box (including a
message box) has an icon only if it does not have a parent frame --- at
least under Windows. If you don't already have a suitable parent frame,
I guess you could suppress the icon by creating a hidden parent frame.
(Be sure to call the `center' method on the frame, since the dialog is
centered over its parent frame.)
