So taking a moment to look at ...
    http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html

500 is a general fault... implying something bad happened and we don't
know how to handle it
503 is a fault implying that the responding server has a problem ...
close but not quite what's happening ...
504 is a fault implying the responding server could not finish due to
some other supporting service having a problem (but implying a proxy
relationship)

I'm afraid I have a third conflicting opinion. I think 504 is a better
fit. But, really nothing really does fit properly. A 500 is probably
fine but a little unsatisfying so I sympathize with your desire to
return something a little more detailed but the fact is nothing in the
w3 descriptions actually do fit.

Hope that helps.
