Whenever I try to save a modified contact, I get the following error:

    [callback] => Array

        )

I have tried running the failing SQL statement from PHPMyAdmin, and it fails there too.    Should I truncate the table "civicrm_log" ? Are there any less drastic approaches?

I am running CiviCRM v. 3.4.7, which was recently restored from a MySQL backup dump.
