Exception while trying to retrieve last commit from shallow repo

In my custom MSBuild task code tries to get last commit hash to put it into one of assembly attributes. Task works very well with repositories cloned with full depth but fails with the following error in repositories with limited depth created with command git clone --depth xx - where xx is number of last commits to clone.

/home/travis/build/DjvuNet/DjvuNet/DjvuNetBuild.Core.targets(20,5): error :
 LibGit2Sharp.NotFoundException: 
object not found - no match for id (d53e5a7166904479d42953bd0f91264f5ace1f6d)
[/home/travis/build/DjvuNet/DjvuNet/DjvuNet.NETStandard2.0/DjvuNet.NETStandard2.0.csproj] 

Code used to retrieve commit data is as follows:

    Repository repo = new Repository(RepoRoot);
    var commits = repo.Commits;
    var commit = commits.FirstOrDefault();

Seems to be libgit2sharp implementation bug as git fully supports enumeration of limited depth repos.

レポートに示されている Repository.Commits エントリポイントから開始し、git clone --depth xx で作成したリポジトリを使って失敗を再現してください。shallow リポジトリの列挙結果を報告されている NotFoundException と比較し、その後、最初のコミットの取得が missing-object エラーなしで成功することを確認してください。issue では特定のテストファイルは指定されていません。
