ERROR in creating an advanced action

Hi, everybody! This unpleasant issue has been briefly mentioned here two months ago by another Drupal user. Since then, Workflow module and Drupal core have been updated several times. However, the issue unfortunately has NEVER been fixed anyway. Now I'd like to be more specific in describing it.
If you use Workflow 7.x-2.4 in Drupal 7.30, you can go to admin/config/system/actions and find the CREATE AN ADVANCED ACTION select list at the bottom of the page. Unfold it, please, and try to select "Change workflow state of post to new state...". You will get nothing! Instead of creating the chosen operation that is NECESSARY for your work, the programm will stop working and show you an empty page. And then you will see the following long list of errors:

Notice: Undefined index: entity_type in workflow_vbo_given_state_action_form() (line 70 of /home/fiatpctr/foton-pct.ru/dr7/modules/workflow/workflow_vbo/actions/given.action.inc).

That is really very annoying, believe me! And I wonder how many other people have been suffering from this problem:((((
