Big 1D field causes SIGSEGV upon app launch when saved gui state has field viewer open

[DickJC123]

// To recreate the problem:
// Run the app below.
// Click on the counter field to display it.
// Exit the app.
// Re-launch the app (window will now have field displayed, but JVM SIGSEGV occurs).
object GuiStateBug extends CogDebuggerApp (new ComputeGraph{
val counter = ScalarField(10000000) // 10 million elements (1 million is OK)
counter <== counter + 1f
