Comment 0 for bug 1902452

I'm trying to save a picture that is 5100x51000 and it crashes whenever I try to save, or undo. It is really annoying because I keep trying to save my image, but it crashes and I have to start over.

It throws an unhandeled exception:

System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ArgumentNullException: Value cannot be null.
