Internal ArgumentNullException during Repository.Reset

[jasonmalinowski]

We have a tool that regularly runs on a repository to migrate changes between several different repositories. As a part of the process, we do a soft reset of a submodule, which periodically (around one time per week) fails with an ArgumentNullException:

Unhandled Exception: System.ArgumentNullException: Value cannot be null.
Parameter name: SafeHandle cannot be null.
    mscorlib.dll!System.StubHelpers.StubHelpers.SafeHandleAddRef(System.Runtime.InteropServices.SafeHandle pHandle, ref bool success) Line 1664
    LibGit2Sharp.dll!LibGit2Sharp.Core.Proxy.git_reset(LibGit2Sharp.Core.Handles.RepositorySafeHandle repo, LibGit2Sharp.ObjectId committishId, LibGit2Sharp.ResetMode resetKind, ref LibGit2Sharp.Core.GitCheckoutOpts checkoutOptions) Line 2615
    LibGit2Sharp.dll!LibGit2Sharp.Repository.Reset(LibGit2Sharp.ResetMode resetMode, LibGit2Sharp.Commit commit, LibGit2Sharp.CheckoutOptions opts) Line 1002
    LibGit2Sharp.dll!LibGit2Sharp.Repository.Reset(LibGit2Sharp.ResetMode resetMode, LibGit2Sharp.Commit commit) Line 985

Unfortunately, I do not have a specific repo; every time this happens a rerun works properly again.

Version Consumed: 0.22. I'm not aware of this happening in an earlier version, but we had enough bugs in the tool itself that it's quite possible we never picked this up in the noise.
