There is no automatic disconnection when the 'receiver' is destroyed because
it's a functor with no QObject. However, since 5.2 there is an overload which
adds a "context object". When that object is destroyed, the connection is
broken (the context is also used for the thread affinity: the lambda will be
called in the thread of the event loop of the object used as context).

In some cases the Apply or OK buttons will not save settings because of section
that was active in the moment of applying. For example made change in one
section, change to another and click Apply. The change will not be applied.
