Difficult to say without a short, complete example that demonstrates the problem. The user data is correctly owned by the QTextDocument that the highlighter is operating on. However there may not be a reference to the document in your application - particularly if you created the highlighter by passing a QTextEdit to its ctor. I'll make a change in tonight's snapshot to address that.
