Jenkins external download md5sum mismatch

Hi,

http://ci.libreoffice.org/job/lo_gerrit_master/16453/Gerrit=Gerrit,Platform=Linux/console
http://ci.libreoffice.org/job/lo_gerrit_master/16453/Gerrit=Gerrit,Platform=MacOSX/console

This are build logs of https://gerrit.libreoffice.org/25673/

On both platforms, it successfully downloads the tarball, but then
complains of an md5sum mismatch. However, I get the right md5sum:
