Exception: Could not find caller class: originating method call is obscured.

setup:
Drupal 7.12
I have a development site running on Mamp php 5.3.6 and production site on linux php 5.2.7
Using Media 7.x-1.2

problem
On the development site everything works ok, but on the production site when adding a vimeo video, I get the following error
Exception: Could not find caller class: originating method call is obscured. in get_called_class() (line 38 of {path to root website}/sites/all/modules/contributed/styles/includes/php/get_called_class.inc).

Looking in the include file get_called_class.inc there should be no problem in php 5.2.4 +
