I've inserted a delay in TextMorph>>paragraph when not running in the ui 
process to simulate getting interrupted while building the new paragraph 
and it does recreate your errors, including the warning message from MC. 
I still have not convinced myself that such an interrupt is a high 
enough probability to account for the number of times you have seen this 
error. But, perhaps some combination of factors in your image make it 
more likely. In any event, I think moving the actual updating of the 
TextMorph to the UI process would be a good thing on general principles.

Cheers,
Bob
