Yes there is no Ruby debugger, and even if there was one, you wouldn't  
probably be able to discover the problem, because in this case it  
looks like a GC bug (I suspect the @layoutManager ivar is prematurely  
collected).

I double-checked that testing has the same code than trunk (modulo a  
change that I just committed, there were some debugging code in  
CircleView).

I also checked with some people that CircleView works fine for them.

So you run 10.5.3. Do you run a PPC or an Intel machine?
