Fatal error for Feed to Post

I am trying to import feeds into posts but every time and with different feeds and settings I am getting the following error.

Fatal error: Cannot use string offset as an array in /home/domain/public_html/mysite/plugins/wp-rss-multi-importer/inc/import_posts.php on line 617

I’ve tried with youtube feeds e.g.
http://gdata.youtube.com/feeds/base/users/AlJazeeraEnglish/uploads?alt=rss&v=2&orderby=published&client=ytapi-youtube-profile
Or news feeds
http://www.france24.com/en/monde/rss
http://www.telegraph.co.uk/news/worldnews/rss

What I really care about is the youtube feeds, I want to import my channel videos as posts, but I can’t get any feeds to work.

What could be at fault here?
