[Plugin: Private Messages For WordPress] Bulk delete error

Running v2.1 of the plugin. Using the template file and viewing the private messages in a standard page (As oposed to viewing through the dashboard, if the user selects all items in the inbox/outbox then it doesn’t select any items, if delete is then selected an error is reported:

Fatal error: Cannot break/continue 1 level in /~/wp/wp-content/plugins/private-messages-for-wordpress/pm4wp.php on line 771

Same result can be achieved by not selecting any items to bulk delete using the dashboard messages menu, and then selecting delete.

Is there a quick fix for this?
