Conflict with YARPP

There seems to be a conflict with YARPP and YARPP Experiments.
Since the last update of those 2 plugins, la petite url doesn’t work anymore. When I try to access a short URL, I get a blank page with the following error in my apache log file:

[Sun Mar 10 18:00:26 2013] [error] PHP Fatal error:  Call to a member function get_option() on a non-object in /wp-content/plugins/yet-another-related-posts-plugin/yarpp.php on line 54

[Sun Mar 10 18:02:25 2013] [error] PHP Fatal error:  Call to undefined function yarpp_get_option() in /wp-content/plugins/yarpp-experiments/yarpp-experiments.php on line 364
