QContact::clearDetails() does reset the type to QContactType::TypeContact, other than specified

API dox of QContact::clearDetails says:
"This function does not modify the id or type of the contact."
http://doc.qt.nokia.com/qtmobility-1.2/qcontact.html#clearDetails

But the implementation does that, resets the type to QContactType::TypeContact:
QContactType contactType;
contactType.setType(QContactType::TypeContact);
contactType.d->m_access = QContactDetail::Irremovable;
d->m_details.insert(1, contactType);
