Error after uploading a file

Hi,
when trying to upload an image into a gallery I take this error:
PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'test6.image_dimensions' doesn't exist: SELECT 1 AS expression FROM {image_dimensions} image_dimensions WHERE ( (fid = :db_condition_placeholder_0) ) FOR UPDATE; Array ( [:db_condition_placeholder_0] => 2 ) in file_entity_image_dimensions() (line 229 of /var/www/test6/sites/all/modules/file_entity/file_entity.file.inc).
thanks
