function jumpUrl does not write the filesize to the header of the download document. The effect is the browser download-window show up unknow filesize and cannot calculate the download time.
function is in
typo3_src/typo3/sysext/cms/tslib/class.tslib_fe.php

Patch: add the line
header('Content-Length: '.filesize($this->jumpurl));
to the function jumpUrl (see the complete patched function in additional informations)
