It will show the first time it's loaded, but after it's cached, there is no slideshow.
template_preprocess_bxslider_views_slideshow_main_frame() isn't executed if the View is cached.
Strange my views @ http://mschudders.equality-sports.com/bx-slider-carrousel?from_drupal=true are also cached but they still show up.
Do you have default caching of any additional caching modules/layers ?
My mistake - you're right. I had a patch applied to Views that seemed to be the problem.
