RichText incorrect MIMEType and MIMEData

Drag text from Safari webbroser and drop it onto Qt application gives incorrect MIMEType/MIMEData. The richtext contents are recognised as plaintext by the Qt.
However if you drop the same contents onto Microsoft word or MAC TextEdit application it recognise/render the same contents as rich text.

The bug is easily reproducible using the dropsite example application provided with Qt.

Steps to reproduce:

1) Open the following webpage in Safari web browser
http://uk.biz.yahoo.com/dealwithdebt/managingdebt.html

2) Run Qt\examples\draganddrop\dropsite application

3) Select the richtext from Safari web browser (i.e. "Managing debt" paragraph) drag and it drop onto dropsite application window

4) In the application window look under tablewidget's "Format" column .. It shows text/plain mimeType of the dropped data
