Field Group conflicts with Ctools module and Biblio [#1328916]

While managing fields in a content type, the following error appears when enabling the Field Group module:

Notice: Undefined property: stdClass::$identifier in ctools_export_load_object() (line 442 of /var/www/sites/clients/umiacs/dev/docroot/sites/all/modules/ctools/includes/export.inc).
Notice: Undefined property: stdClass::$identifier in ctools_export_load_object() (line 446 of /var/www/sites/clients/umiacs/dev/docroot/sites/all/modules/ctools/includes/export.inc).
Notice: Undefined property: stdClass::$identifier in ctools_export_load_object() (line 442 of /var/www/sites/clients/umiacs/dev/docroot/sites/all/modules/ctools/includes/export.inc).
Notice: Undefined property: stdClass::$identifier in ctools_export_load_object() (line 446 of /var/www/sites/clients/umiacs/dev/docroot/sites/all/modules/ctools/includes/export.inc).

This error appears on the following admin pages:
/admin/structure/types/manage/ANY_CONTENT_TYPE/fields
/admin/structure/profiles/manage/ANY_PROFILE_TYPE/fields
/admin/structure/types/manage/biblio/fields

Disabling the module makes the error messages disappear.

Did you run all the update hooks? Identifier is very important for field_group, and where added a long time ago.
If this is done, and you still got a problem. Please check your database. The field_group table should have identifiers.
