Review request for Telepathy.


Description (updated)
-------

Using Tp::ContactFactory causes crash in KTp::ContactsListModel::data(), because cast to KTp::Contact fails and then we dereference a null pointer.

Question of the day: could we add something like 

Q_ASSERT_X(contact.isNull(), "KTp::ContactsListModel::data()", "Cast failed. Did you forget to use Ktp::ContactFactory again?");

to data() to make it easier to spot the real problem? It took me good 15 minutes to figure out where the null pointer comes from and why the cast fails.
