* Disconnect an indirect connection.

* For this to work properly, dg has to be exactly the same as
* the one passed to connect. So if you used a lamda you have to
* keep a reference to it somewhere if you want to disconnect
* the connection later on. If you want to remove all
* connections to a particular object use the overload which only
* takes an object paramter.
