Why get my constraints broken?
Why get my constraints broken?

I have a xib-file with an NSView (content view of a tab of an NSTabView) called TabTextView.
Inside this TabTextView I have an NSScrollView (containing an NSTextView) called ScrollText which:
- has a top vertical distance to it's superView (TabTextView) of 12
- has a height of 33 or more
- has a bottom vertical distance to it's superView (TabTextView) of 17.
Sounds quite reasonable to me.
But when I load this xib file I get some strange messages (hex addresses edited for readability):
... Unable to simultaneously satisfy constraints:
(
"<NSLayoutConstraint:0X1 V:[ScrollText(>=33)] (Names: ScrollText:0XB )>",
"<NSLayoutConstraint:0X2 V:[ScrollText]-(17)-| (Names: TabTextView:0XA, ScrollText:0XB, '|':NSView:0XA )>",
"<NSLayoutConstraint:0X3 V:|-(12)-[ScrollText] (Names: ScrollText:0XB, TabTextView:0XA, '|':NSView:0XA )>",
"<NSAutoresizingMaskLayoutConstraint:0X4 h=--& v=--& V:[TabTextView(0)] (Names: TabTextView:0XA )>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0X1 V:[ScrollText(>=33)] (Names: ScrollText:0XB )>
... Unable to simultaneously satisfy constraints:
(
"<NSLayoutConstraint:0X2 V:[ScrollText]-(17)-| (Names: TabTextView:0XA, ScrollText:0XB, '|':NSView:0XA )>",
"<NSLayoutConstraint:0X3 V:|-(12)-[ScrollText] (Names: ScrollText:0XB, TabTextView:0XA, '|':NSView:0XA )>",
"<NSAutoresizingMaskLayoutConstraint:0X4 h=--& v=--& V:[TabTextView(0)] (Names: TabTextView:0XA )>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0X2 V:[ScrollText]-(17)-| (Names: TabTextView:0XA, ScrollText:0XB, '|':NSView:0XA )>
What am I doing wrong?
I don't like these warnings, and I resent the breaking of my constraint V:[ScrollText(>=33)] which I put there for a good reason.
Kind regards
Gerriet.
P.S. 10.7.3, Xcode 4.3.2
