Bugger that, wrong issue, sorry.
Ok, we'll have a look, probably some synchronization problem.

Does this still happen. Anyone some steps to reproduce.
I have not seen it for a long time.
I've got today when I pasted fragment of code to the file under cvs. Unfortunately I cannot reproduce it, after undo and redo no exception has occurred. Attaching new stacktrace since the line numbers are a little bit different.

moving opened issues from TM <= 6.1 to TM=Dev
Stacktrace is very similar to 130628. Looks like the same problem of sync between AnnotationViewDataImpl.getMergedMarks and AnnotationViewDataImpl.computeTotalStatus. Since 130628 has bunch of more recent stack traces closing this as a dup of it. *** This issue has been marked as a duplicate of 130628 ***
