problem after update : call_user_func_array()

Hello,

after the update to the 6.X-1.0 version, I have these warning at the top of my site.
Do you have an Idea ? I can't see my primary links menu and the title of the site.

* warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'phptemplate_menu_local_tasks' was given in /var/www/drupal/includes/theme.inc on line 617.
* warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'phptemplate_breadcrumb' was given in /var/www/drupal/includes/theme.inc on line 617.
