Some file can't be tracked by Commits.QueryBy(path)

I use to following code to track the latest change for a special file. But I found some file can't be tracked while the others can be tracked correctly.

var latestCommitLog = repository.Commits.QueryBy(file);
if (latestCommitLog.Count() > 0)
{
        var latestCommit = latestCommitLog.First().Commit;
}
else 
{
        // no history
        // some file has be pushed to repository but can't be tracked.
}

該 issue 只指出了 repository.Commits.QueryBy(file)；首先使用一個能正常運作的受追蹤檔案和一個無法正常運作的受追蹤檔案重現問題，同時記錄它們的路徑詳細資訊和 repository 狀態。追蹤該 API 呼叫，以確定結果為空的原因。完成的標準是：出問題的檔案回傳其最新 commit，並且有一個 regression test 涵蓋該情況。
