After this I clicked the top menu, then on Enclosures, then on the url and "Open url externally" the browser opens and ask to play with media player or to download. Clicked download and it is working, also media player is working. The button "Open URL in browser" is not working.
edit: My test were done with the latest version from git and qssl correction and user-agent fix for app and client which hopefully solves all download problems. Released under cutenews 1.3.2
