Error while performing database update for Entity Reference

Hello,

We tried to update the Entity Reference Module and get the error below.

Error while performing database update for Entity Reference 7.x-1.3

An AJAX HTTP error occurred. HTTP Result Code: 200 Debugging information follows. Path: /update.php?op=selection&token=kuRJfmgtX1gyvq-Hb_-qqJNNXbkLACpw4sfFa3j-sLQ&id=96&op=do StatusText: OK ResponseText: Fatal error: Unsupported operand types in /home/www/drupal7/includes/database/mysql/schema.inc on line 86

The update process was aborted prematurely while running update #7100 in entityreference.module. All errors have been logged. You may need to check the watchdog database table manually.
