Comment (by acid2):

 Just a quick update on this. If I change my http_proxy variable from
 wwwcache.lancs.ac.uk to wwwcache3.lancs.ac.uk, this problem doesn't
 happen. It seems that somewhere in the haskell code, something is tripping
 up by the fact that wwwcache.lancs.ac.uk is actually a round-robin
 dispatch (or something...) to other proxy servers.
