Changing-chart-scale-to-higher-scale-than-ScaleInd-causes-exception

The following may be rare for somebody to do, but nevertheless I thought you guys should know about this exception...

Bring up a chart and set symbol to U.
Set scale to 1 minute
Activate streaming.
Drag ScaleInd indicator onto chart and set settings as follows: Indicator to Close, Compress to Scale to 5 minutes, and the Pane to Price.
Everything is OK.
Change the chart's scale to 15 minutes.
Exception occurs:

System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')
