Adding:

            if (!startOfParagraphToMove.deepEquivalent().node()->parent()) {
                // Inserting the break resulted in deleting the node we're
going to move.
                return;
            }

Right after:

        if (startOfParagraph(endOfInsertedContent) == startOfParagraphToMove) {
            insertNodeAt(createBreakElement(document()).get(),
endOfInsertedContent.deepEquivalent());

In ReplaceSelectionCommand fixes the bug, but when attempting to drag the third
time a different crash occurs.

Seems to me any place in ReplaceSelectionCommand that does mutation needs to
make sure the document is sane before continuing. This is based on my limited
knowledge of webkit though, so I could of course be completely wrong.
