It is not only IVIM Perspective, it occurs in the same way in MitkWorkbench.

Here the workflow:

1. Close all Perspectives
2. Open 'Research' Perspective
3. Load some test image
4. Open Segmentation Plugin
5. 'New Segmentation', enter the name and confirm --> CRASH

The Workbench version came from the release nightly dartclient ( the Workbench build) mbi046.

The debugger stopped at:

QmitkSlicesInterpolator::SetCurrentContourListID()

l. 1062: mitk::Vector3D spacing = workingNode->GetData()->GetGeometry( m_LastSNC->GetTime()->GetPos() )->GetSpacing();

It seems that the m_LastSNC->GetTime() returns a null-pointer which is left unchecked and thus the ->GetPos() runs into a SIGSEGV

It can also be reproduced by:

1. Create segmentation in a perspective where it works (e.g. the Diffusion perspective)
2. Close close all perspectives

->Crash

In the same line for the same reason

I guess this bug might be related to T18444 on which Stefan is working. So you might want to keep each other updated.

User hering has pushed new remote branch:

bug-18477-CrashInSegmentationAfterClosedPerspectives

T18444 seems to be something different, the crash there happens in the image statistics

Branch merged into releases/2014-10.
