For instance in the following code, where m_manager is a Telepathy::Client::AccountManager:

    m_accounts = m_manager->allAccounts();
    foreach( int i = 0; i < m_accounts.size(); i++ )
    {
        connect( m_account.at( i )->becomeReady(),
            SIGNAL(finished(Telepathy::Client::PendingOperation *)),
            SLOT(accountReady(Telepathy::Client::PendingOperation *)));
    }

Standard stuff. allAccounts returns QSharedPointer's which are stored in a QList (m_accounts). In the accountReady slot there is however no way to access the QSharedPointer, so if accountReady wants to share the account with another class it can't (at least not without additional hacks). 

The reason PendingAccountReady return a QSharedPointer is because some accounts are created independently of AccountManager, so the strong pointer wouldn't be available to PendingAccountReady. 

Something like KSharedPtr could solve it, since KSharedPtr keeps the refcounter in the object instead of the pointer. QExplictlySharedDataPointer might work as well.
