Not done php for a while but,
A search for "Call to a member function  xyz() on a non-object" shows
that apparently  at that invocation function was getting called on a
null/empty object. 

eg. 
https://www.drupal.org/project/entity_translation/issues/2648062
so a check on var before invoking method on it.
or $_SESSION['obj_ClientConfig'] is empty?

Also suggest to compare output of  'locale -a'  on Debian 7 & Ubuntu
14.04 . Should have C, C.utf8 en_US.utf8 in the list.
