commit 9056a51ccd598060bb52d4ef0354410e0c30b58e
Author: Andrej Kacian <ticho at claws-mail.org>
Date:   Mon May 15 22:22:13 2017 +0200

    RSSyl: Stop earlier when an invalid feed is encountered.
    
    This fixes a bug where feeds get renamed to "Untitled feed"
    if their URL starts serving e.g. a HTML document instead
    of proper content.
