Call-time pass-by-reference has been deprecated

Hi. I got this msg "Call-time pass-by-reference has been deprecated in C:\wamp\www\drupal\sites\all\modules\flag_weights\draggableviews_handler_flag_weights.inc on line 14" whe I enter in my Bookmarks and i get a bigger one when i try to save the Bookmark Flag Views Page.

I´m using today´s most recent version of Flags (6.x-2.x-dev), Draggable Views (6.x-3.x-dev) & Flag Weights (6.x-1.x-dev)

Any Hint?

Btw Thanks for your work
