solr.BinaryField does not return Base64-encoded string

[elben]

I have a a solr.BinaryField field. When I query, I see:

<str name="raw">[B:[B@254ce181</str>

@tjake suggested a patch (https://gist.github.com/1352769), but this produces a null pointer exception (https://gist.github.com/1352766).

According to this thread, binary blobs are send/received to Solr as base64.
