Can't reproduce / #2983

Hi Burger,

I spent some time playing around with those stuff, but I cannot reproduce this behavoir. I will work, if:

• The current user (PM) has neither "RIGHT_VIEW_ALL" nor "RIGHT_EDIT_ALL" (which included RIGHT_VIEW_ALL)
• The private task has not been created by the other persons.

I will create the new users to the demo installation.

This is really a serious issue and I am eager to remove any uncertanties about this.
