    Bug 628324 â?? Invalid reads in gdbus-export test
    
    Looks like we forgot to ref the returned GVariant in
    g_dbus_proxy_call_finish().
    
    It's a good question why code using g_dbus_proxy_call() and
    g_dbus_proxy_call_finish() worked in the first place - probably the
    answer is that no-one really used these APIs.
