Issue: Android app, infected file found, bad feedback

Actual behaviour

When uploading a eicar file (file that is marked as a virus) the android app returns "upload failed - Snsupported Media Type".

Expected behaviour

When uploading an infected file, the user is given a clear feedback and the applications stops from trying to upload that file again.

Steps to reproduce

  1. Upload a eicar file from the Android app.
  2. Receive feedback that does not explain the issue.

Can this problem be reproduced with the official owncloud server?
