The following probably won't be much help, but with a quick Logos search, this is what I am seeing:
"Attacks on the “Sentences”; Other Works
In spite of the cautious objectivity of the whole treatment, some of the propositions laid down in the “Sentences” were considered erroneous in after years. Mention has been made above of the attacks on Peter’s doctrine of the Trinity and his Christology. Walter of St. Victor asserts that at the Lateran Council of 1179 it was proposed to condemn the “Sentences,” but other matters prevented a discussion of the proposal. From the middle of the thirteenth century the University of Paris refused its assent to eight propositions, of a highly technical character, it is true, and Bonaventura declined to press them. Others were afterward added; but these objections did not interfere with the general popularity of the work, which had increased to such an extent by Roger Bacon’s time that he could complain (c. 1267) that lectures on it had forced those on Scriptural subjects into the background. Besides the “Sentences,” other extant works of Peter Lombard are Commentarius in psalmos Davidicos (first printed Nuremberg, 1478; in MPL, cxci. 31–1296) and Collectanea in omnes D. Pauli epistolas (first printed Paris, 1535; in MPL, cxci., cxcii.)—both collections, in the manner of medieval Catenæ (q.v.), of quotations from patristic and early medieval theologians, with occasional independent remarks. A few unpublished manuscripts, some of them of doubtful authenticity, remain in various places. Of these the most important for a complete knowledge of the author are two manuscripts, one early thirteenth century, the other fourteenth, in the Bibliothèque Nationale at Paris, containing twenty-five festival sermons representing a moderate type of medieval mystical theology, dominated by allegorical exegesis, but making some excellent practical points. Extracts from them are given by F. Protois (P. Lombard, son épôque, sa vie, ses écrits et son influence, pp. 126–147, Paris, 1881)."

"After his death, one of the propositions contained in it (“Christus, secundum quod est homo, non est aliquid”) was condemned by pope Alexander III."
After work, I can spend a little more time investigating. I do remember Justo Gonzalez discussing this in the first volume of his Church history.
