PDO error on installation

Upon installing the module, I encountered this error:

PDOException: SQLSTATE[42000]: Syntax error or access violation: 1101 BLOB/TEXT column 'element' can't have a default value: CREATE TABLE {node_accessibility_problems} ( `id` BIGINT unsigned NOT NULL auto_increment COMMENT 'The primary key used to represent this problem.', `nid` INT unsigned NOT NULL DEFAULT 0 COMMENT 'The node’s ID from node.nid.', `vid` INT unsigned NOT NULL DEFAULT 0 COMMENT 'The node’s version ID from node.vid.', `test_id` BIGINT unsigned NOT NULL DEFAULT 0 COMMENT 'The numeric ID from quail_api_tests.id, representing a specific error.', `line` INT unsigned NOT NULL DEFAULT 0 COMMENT 'The line number in which the error happened.', `element` TEXT NOT NULL DEFAULT '' COMMENT 'A snippet of the code that failed validation.', PRIMARY KEY (`id`) ) ENGINE = InnoDB DEFAULT CHARACTER SET utf8 COMMENT 'Node validation problem statistics.'; Array ( ) in db_create_table() (line 2684 of /home/testv71/htdocs/includes/database/database.inc).

I was able to avoid the failure and complete the installation by modifying node_accessibility.install to change this clause:

      'element' => array(
        'description' => st("A snippet of the code that failed validation."),
        'type' => 'text',
        'not null' => TRUE,
        'default' => '',
      ),

to:

      'element' => array(
        'description' => st("A snippet of the code that failed validation."),
        'type' => 'text',
        'not null' => TRUE,
      ),

It was necessary to disable and re-enable the module after the change to allow the install script to run and create the necessary tables.
