How to reproduce:

• Load an image
• Create a segmentation on that image
• Activate the measurement view and select the image ( so that it appears in the measurement view GUI)
• close the application --> hangs in Debug Mode, double free/corruption on Release

Reason:

The QmitkMeasurementView::NodeRemoved is called, the GetDerivations call with TNodePredicateDataType< PlanarFigure > is not empty ( the 3d interp contours ?? ) and the view makes an attept to remove the figures from the d->m_DataNodeToPlanarFigureData member map. But the map object is empty ( because the nodes were not created by the measurement view) but still the erase method is called on a invalid map::iterator.

Proposed solution:

Check the validity of the d->m_DataNodeToPlanarFigureData object and of the iterator object returned by the find() method.
