unsubscription error

The following code outputs nicely while the stream is running output, but then when it's done emits an error.
##### the code

``` coffeescript

#[...]
query = new QueryStream("select * from raw_custom_entries where description ilike '%sesame%' limit 290")
stream = client.query(query)
stream.on 'end', ->
c '\n are done'
++counter
c color.red(counter)
done()
willow = rx_node.fromStream stream
# stream.pipe(JSONStream.stringify()).pipe(process.stdout)
willow.subscribe (stuff)->
c color.green('willow has stuff'), stuff

```
