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

從重現中的 Rebase.Start 呼叫開始，追蹤它經過 LibGit2Sharp.Rebase.Start、Core.Proxy.git_rebase_init 和 Core.Ensure.HandleError 的流程。在 Windows 10 上使用 LibGit2Sharp 0.26.0 和提供的分支參數進行重現，然後將 native 失敗與預期的 rebaseResult.Status 進行比較。當間歇性情況得到解釋，並且無需空錯誤例外即可處理時，即視為完成。
