IMCE file browser toolbar disappears and files no longer clickable

The one error that showed up in Firebug.

this.data is undefined
[Break On This Error] 	
this.forms = this.data['forms'];

Traced it to clientside_validation.js

/**
* local copy of all defined forms
* @memberof Drupal.clientsideValidation
* @type array
* @readonly
*/
this.forms = this.data['forms'];

Creating a break in Firebug at the point above doesn't change anything but a break at the following function then stopping the page loading brings the toolbar buttons back.

/**
* Drupal.behaviors.clientsideValidation.
*
* Attach clientside validation to the page or rebind the rules in case of AJAX calls.
* @extends Drupal.behaviors
* @fires clientsideValidationInitialized
*/
Drupal.behaviors.clientsideValidation = {
attach: function (context) {
if (!Drupal.myClientsideValidation) {
Drupal.myClientsideValidation = new Drupal.clientsideValidation();
}
else {
var update = false;
jQuery.each(Drupal.settings.clientsideValidation.forms, function (f) {
if ($(context).find('#' + f).length || $(context).is('#' + f)) {
update = true;
}
});
//update settings
if (update) {
Drupal.myClientsideValidation.data = Drupal.settings.clientsideValidation;
Drupal.myClientsideValidation.forms = Drupal.myClientsideValidation.data['forms'];
Drupal.myClientsideValidation.groups = Drupal.myClientsideValidation.data.groups;
Drupal.myClientsideValidation.bindForms();
}
}
/**
* Let other modules know we are ready.
* @event clientsideValidationInitialized
* @name clientsideValidationInitialized
* @memberof Drupal.clientsideValidation
*/
jQuery.event.trigger('clientsideValidationInitialized');
}
};
