[Mac] QRawFont::fromFont not working correctly

On Mac OS X 10.6.3:
QFont font = QFont("Wingdings"); //font.family() == "Wingdings"
QRawFont rawFont = QRawFont::fromFont(font); //rawFont.familyName() == "Lucida Grande"

rawFont.familyName() should return "Wingdings" instead of "Lucida Grande".
On Windows, this code is OK.

-------------------

Wingdings is just an example.
Below is log of font.family() and rawFont.familyName() result. (Qt 4.8.6, MacOS X 10.6.8)
There are some fonts that have mismatch family: Baghdad-Lucida Grande, Bookshelf Symbol 7-Lucida Grande, Corsiva Hebrew-Apple Chancery, DecoType Naskh-Lucida Grande, ...
Thus, I see an error over "Bauhaus 93" font. Is this trouble a CoreText problem?
