It only relates to it insofar as it made my recovery process slightly 
more tortuous. I had to read in the 'corrupt' stack file and rename 
its mainstack and all its substacks; then I had to reproduce the 
structure of my app with the mainstack and substacks all having their 
original names, and then I had to copy over all the cards, scripts, 
properties etc. It worked (I was not sure that it would, because I 
had no way of knowing where the bad 'breakpoint' information resides 
- maybe in hidden properties or something). Anyway so far the 
rejuvenated app is working using RunRev 2.1.

The transfer process took about an hour I suppose, so I was glad my 
app wasn't any bigger. I admit that the renaming phase was trivial 
compared with the other stuff. I guess I could have written a program 
to do the recovery automatically, but it would have taken quite a 
time to debug.

However my main objection to the "can't have two stacks with the same 
name" restriction is the same as yours - if a library (however 
defined) just happens to contain a stack with a name I've already 
chosen for a stack in my main app, I'm in trouble. I do have one or 
two other suspicions about the way scoping works in runrev (for 
example, are object IDs unique or not?) - but I haven't done enough 
work on this to make an informed comment.
