What steps will reproduce the problem?
1. Use the find/replace dialog with the "Highlight" option to create some 
highlights in the text
2. Call setText()

What is the expected output? What do you see instead?

The following exception is thrown:

I was not able o exactly recreate the issue with latest r128 code, but it did 
one 
throw an NPE after setText and some undoes.
That issue should not happen now.

Fixed in r129.
