I know this thread is quite old, but as i had the same problem here's my solution to it:
I downloaded the fix mars posted in this thread and changed one line:
$canEdit = ($this->user->authorize('com_content', 'edit', 'content', 'all') || $this->user->authorize('com_content', 'edit', 'content', 'own'));
to
$canEdit = $this->item->params->get('access-edit');
Attached you can find the complete file. As mars mentioned in his post it is to be uploaded to
