For having the WF line in GWT toolbar my user needs to have the Role (publish all) !!!

The idea of such a WF toolbar is having the shortcut of WF actions (publish current page,..)the user can perform on the pages on which he has the editing or publishing roles, right? but it seems actually the user should have the role 'Publish all' for being able to have this line in his toolbar, .not logic? its seems to me we don't take in consideration the correct role in toolbar.xml for displaying this toolbar .
I'll investigate more..
