Could you please add a break point in line 718 of the file 
GSLayoutManager.m and report back the back trace you get. That way we 
should be able to understand what is going on. Most likely we have a 
background thread that is changing the text while the gui thread is 
trying to lay it out. I am not sure what the best way to handle this 
could be. Maybe throw a specific exception here and handle it in the 
text view? I don't like the idea of adding more locks to the text 
processing.
