I naively tried the registration evaluator with two instances of Pic3D and tried to visualize the resulting registration using.

To reproduce:

1. Open MITK Workbench, load Pic3D two times (rename them so make it easier to distinguish)
2. Open the MatchPoint Algorithm Browser and select MultiModal.rigid.default
3. Open the MatchPoint Algorithm Control, chose both images for moving and target data (no mask) and load the selected registration algorithm
4. Start the registration computation
5. Open the MatchPoint Registration Evaluator, chose both images for moving and target data and select the new registration (could also use the mapped image for the moving image)
6. Change evaluation mode to Color blend

-> Workbench crashes

The minimal workflow to reproduce is:

1. Open MITK Workbench, load Pic3D two times
2. Open the MatchPoint Registration Evaluator, chose both images for moving and target data
3. Change evaluation mode to Color blend
