Opening and resaving pptx file causes "Index was outside the bounds of the array" exception

Opening and then immediately saving the attached file causes an “Index was outside the bounds of the array” exception to be thrown by Aspose.Slides. We are using the latest released version of Aspose.Slides for .NET. The file is a little over a MB, and I’m told by our client that this is because of a very complicated chart object in the presentation, and the stack trace makes me think that handling that chart is what’s causing this issue.

The code for the test was:

Dim Presentation = New Aspose.Slides.Presentation(SourceFile)

Presentation.Save(DestFile, Slides.Export.SaveFormat.Pptx)

The exception message: Index was outside the bounds of the array.

The stack trace:
