Summary	0000046: vtkMRMLScene::GetNextNodeByClass Segementation faults
Description	"if( !this \|\| !this->CurrentScene )" should be "if ( !this && !this->CurrentScene )" Actually if 'this' is not initialized it will check both statements and throws an segfault error because of accessing CurrentScene which is not available. I'm not sure though, if this is how it should work on that place.
