> On DelegatedFileObjects the Listener is registered with a WeakReference
> listener. The original code which did that has a (errounous) duplication of
> listeners. This leads to the problem that the "middle" listener is never
> referenced and therefore imediatelly collected, which in turn leads to
> removal of the "outer" listener.
> I have added a testcase which reproduces the problem and does not fail when
> duplication is removed.
