Unfortunately it's not a public url, and it uses some authorization tokens in the request, so I can't disclose it.
I am using drakma-0.11.5 and chunga-0.4.2 on Ubuntu with sbcl-1.0.15.
I am going to use *header-stream* to see if it gives some clue.

Hmm, it should definitely not just silently return NIL, but we
probably need a tiny little bit more info from you:

Which Lisp?  Which operating system?  Which version of Drakma and
Chunga?  Have you tried to trace the headers when this happens?

 http://weitz.de/drakma/#*header-stream*

Is this a public URL so we can try to reproduce your problem?

Edi.
