Private profile field cancels display of following profile fields

Hi Folks,

consider the following setuop for profile fields. The order is important!

1: First Name: public (shown on profile and list)
2: Name : public (shown on profile and list)
3: Phone: private
4: ICQ: public (shown on profile and list)

Every user is required to fill out name and first name upon registration. Phone number and ICQ are optional.
Peter fills out all four fields, Paul fills out name and ICQ.

Anonymous and authenticated users are allowed to view user profiles (don't know if that matters).

If an anonymous or authenticated user views Peters profile, he sees only the users name.
If an anonymous or authenticated user views Pauls profile, he sees the users name and ICQ number.

Admin or Peter see all four fields of Peters profile.

I guess that the restricted visibility of the filled out phone number in Peters profile breaks the loop that displays the user profile fields.
