I tried ess-developer-add-package, and it seemed to work with one 
glitch.  The glitch is that when the breakpoint came I got the browser() 
in the *R* window, but there didn't seem to be the highlighted window 
with the current code and line.  The unhighlighted version of the window 
was open and available.

So maybe developer steps on tracebug a little bit.

Eventually the tracebug version of the window came back; I can't 
remember exactly what steps I took to do that.
