How to reproduce:

• Switch to probtractdisplaysp branch, since only there the schmahmanpandya slice module exists
• Start OW
• Load T1 image
• Try to connect T1 image with new SchmahmannPandya slice module at connector: t1input

Then the segfault will originate from: @bool WQtNetworkEditor::event( QEvent* event )@ at source:src/qt4gui/qt4/networkEditor/WQtNetworkEditor.cpp@d647ecf2bfe4#L284 due to a failing cast. Why that cast failing is out of my scope since, the return type of that member function is undocumented. Please note that the SchmahmannPandya slice module resides under source:src/modules/schmahmannPandyaSlices/slices@dc8239ab and is a so called compound or container module incorporating the two other modules bodundaryCurvesGMWM and probTractDisplaySP.

Alternatively you can also use the gaussProcess modules to reproduce, since this is also a compound aka container module.
