Within administration/ manage users I received the message : File profile/small.jpg (file guid:0) (owner guid:63) is missing an owner!
I had directly deleted a user from the database rather than deleting from within administration. To fix this I just recreated a user within the database with an owner id of 63. Once I inserted a new record within the elgg_users_entity table with an guid of 63, the error now longer appeared within my elgg site.

You can use Cash's Database validator plugin too... http://community.elgg.org/pg/plugins/costelloc/read/438616/database-validator ... I had this problem and the plugin fixed it really well.
