FullHistory method of FileHistory class, doesn't return actual history

Code:
var _repository = new Repository(@"D:\11");
var commitFilter = new CommitFilter { SortBy = CommitSortStrategies.Topological };
var sdf = _repository.Commits.QueryBy("SPF 711 performance", commitFilter).Select(c => c.Commit).ToList();
doesn't return history, while existing of 7 commits.

Inside the method FullHistory iterating through commits stops when reaching commit
4bf4edccaa9ce3b7f785b14939a3545c627b5dfd because of this code:
var currentTreeEntry = currentCommit.Tree[currentPath];
if (currentTreeEntry == null)
{
yield break;
}

looks like iterator cannot achieve commits which contain a history of the file because of the running into the commit which knows nothing about the file.

FileHistory.FullHistory を見つけ、示されている Repository と CommitFilter を 7 コミットの履歴に対して使用して問題を再現します。コミット 4bf4edccaa9ce3b7f785b14939a3545c627b5dfd での反復を追跡し、currentTreeEntry が null のときに停止するのではなく、メソッドが完全なファイル履歴を返すことを確認します。
