[Haskell-cafe] Hackage upload problem

Hi, I get the following error when I try to upload gf-3.5.tar.gz [1] to Hackage. 400 Error in upload could not extract gf-3.5 directory from gf-3.5.tar.gz I get the same error when I try to Check the previous version, gf-3.4.tar.gz [2], which was uploaded without problems 6 months ago [3], so it seems that something has changed on the server. Does anyone know what it could be that is going wrong? Is there a way to get a more informative error message?
