The bugfix for https://jira.ez.no/browse/EZP-21324 has introduced a regression that leads to a fatal error when editing content with an ezimage attribute.

2013.09 is affected only if you followed the upgrade steps from http://share.ez.no/downloads/downloads/ez-publish-community-project-2013.09/upgrading-from-ez-publish-community-project-2013.07-to-2013.09. If you did, just run the following SQL:

MySQL:
DROP INDEX ezimagefile_co_attr_id_filepath ON ezimagefile;

PostgreSQL:
DROP INDEX ezimagefile_co_attr_id_filepath;
