ArgumentOutOfRangeException when calling UnitOfWork.SaveChanges() with EnableCandidateFixes enabled.

Using LightSpeed 5.0.2276.0.

When calling UnitOfWork.SaveChanges(), prior to any other query, against a LightSpeedContext with EnableCandidateFixes enabled, an ArgumentOutOfRangeException is thrown.

If you look at this snippet from Mindscape.LightSpeed.UnitOfWork.SaveChanges() you can see the do while loop will throw if the entities List is empty, which seems to be the case if no queries have been made in the UOW (or entities attached) prior to calling SaveChanges().

    if (this.Context.\u0087(LightSpeedCompatibilityOptions.EnableCandidateFixes))
    {
      List<Entity> list = new List<Entity>();
      List<Entity> entities = this.IdentityMap.GetEntities();
      do
      {
        Entity entity1 = entities[0];
        entity1.FireEnlisted((EventArgs) null);
        if (this.IdentityMap.Count > list.Count + entities.Count)
        {
          foreach (Entity entity2 in this.IdentityMap.GetEntities())
          {
            if (!list.Contains(entity2) && !entities.Contains(entity2))
              entities.Add(entity2);
          }
        }
        entities.RemoveAt(0);
        list.Add(entity1);
      }
      while (entities.Count > 0);
    }

The attached console app reproduces the issue.
