Can you get any details about why/how it fails? It could well be something
as simple as Yahoo throttling you for too many connections in too short a
time or something; in that case, the error from Yahoo should indicate it,
but if all you get back is a 4xx or 5xx code then it won't be obvious.
(Which may well mean something like running it under strace with +RTS -V0
to see the actual error returned.)
