This is actually a misuse of QVariant. The error you got when compiling was probably due to the fact that ContactModelItem* has not been declared as a MetaType through the Q_DECLARE_METATYPE(ContactModelItem*) macro (http://doc.qt.nokia.com/4.7/qmetatype.html#Q_DECLARE_METATYPE), hence Qt can not recognize it as a type QVariant can hold. The right thing to do is to declare the metatype correctly (you might want to do that at the bottom of ContactModelItem's header), and then use QVariant::value() to extract the type without resorting to hacks. The code you should obtain should look like:

Tp::ContactPtr contact = m_model->data(realIndex, AccountsModel::ItemRole).value<ContactModelItem*>()->contact();

Please check if you had to resort to similar hacks in other portions of the code, and fix them accordingly.
