New Post: Adding keywords to stream

What you encounter is a threading bug that I have introduced when implementing the async framework in Streams.

As a work around from this bug (on which I will work as a priority), please add the following code to yours.

filteredStream.StreamStopped += (sender, args) =>
{
           filteredStream.StartStreamMatchingAllConditions();
};

I know that this is not ideal but the bug is not trivial so I will have to think about this before releasing a fix.
