Summary: It was pointed out to me by James McKernan that there is a mistake in the proof of Proposition 2.7 [Doc. Math., J. DMV 9, 471--486 (2004; Zbl 1072.14048)]. Namely, it is stated (and ``used'') there that the complement to a smooth conic in \(\mathbb P^2\) is simply-connected. This is obviously false; indeed, the fundamental group is cyclic of order two. This mistake is, however, easy to deal with.
