Title:
  repeated random undo/redo in node editor throws exception

Status in HypeDyn:
  New
Status in HypeDyn 2.1 series:
  Invalid

Bug description:
  In a new node, I typed in some text, created a link, and then typed a
  bit more text. Then I randomly pressed undo and redo a few times, and
  the text got messed up, plus the following exception was thrown:
