Exception During Rebase: No error message has been provided by the native library

I've seen this happen a couple times out of a hundred, so it is difficult to reproduce. When it has happened, I've rebased successfully from the command-line without any conflicts; then when I re-run this it still fails.

Stack Trace

LibGit2Sharp.LibGit2SharpException: No error message has been provided by the native library
at LibGit2Sharp.Core.Ensure.HandleError(Int32 result)
at LibGit2Sharp.Core.Proxy.git_rebase_init(RepositoryHandle repo, AnnotatedCommitHandle branch, AnnotatedCommitHandle upstream, AnnotatedCommitHandle onto, GitRebaseOptions options)
at LibGit2Sharp.Rebase.Start(Branch branch, Branch upstream, Branch onto, Identity committer, RebaseOptions options)

Reproduction steps

var rebaseResult = repository.Rebase.Start(featureBranch, masterBranch, null, _getIdentity(repository), new RebaseOptions());

Expected behavior

A rebaseResult.Status

Actual behavior

An exception

Version of LibGit2Sharp (release number or SHA1)

0.26.0

Operating system(s) tested; .NET runtime tested

Windows 10

再現手順の Rebase.Start 呼び出しから始め、LibGit2Sharp.Rebase.Start、Core.Proxy.git_rebase_init、Core.Ensure.HandleError を経由して追跡します。Windows 10 上で、LibGit2Sharp 0.26.0 と指定されたブランチ引数を使って再現し、その後、ネイティブの失敗と期待される rebaseResult.Status を比較します。断続的に発生するケースが説明され、空のエラー例外なしで処理されれば完了です。
