The Applications crashes on opening a saved project.

The project consists of a .nrrd-File (we used the Pic3D)
and a simple Segmentation.

Workflow to reproduce the Bug would be

1. Loading a picture
2. Creating a segmentation using Segmentation-Tool
3. Saving the progess
4. Closing Project (or the Workbench)
5. Reloading the saved Data

-> Crash

If you just close the project, a message apperears shortly before crash telling the user, that "no image information at this position" is available

This was tested on Win7 and Linux Ubunutu 12.4 both in x64
