Can't download files via Chrome on Android devices.

[savely-krasovsky]

I faced with very strange problem. ALL desktop browsers download all types of files as should. But mobile webkit-based browsers on Android doesn't! They just say me, that
[filename] download failed due to server issues.

Steps to reproduce

1. Take Android phone.
2. Try to download any file via web-version by Chrome
   (or something WebKit-based. With other browsers all works as should).

Expected behaviour

The download should be successful.

Actual behaviour

Browser tell us, that download failed due to server issues

I get it by debuging directly via USB-connection in desktop Chrome!

This seems to be the exact same bug as #342 (comment)

This is already reported upstream (Chrome for Android). Could you try the download with a different browser?
