How to reproduce: * load deterministic tracts aka fibers * create ROI, move to tracts, move a bit around * close openwalnut You will get this segfault: <pre> 0#22:30:29#math@ipansen# OpenWalnut/build/release >bin/openwalnut OpenWalnut -- Version: 1.2.5+hg5231 ( http://www.openwalnut.org ) Copyright 2009-2010 OpenWalnut Community, BSV@Uni-Leipzig and CNCF@MPI-CBS For more information see http://www.openwalnut.org/copying This program comes with ABSOLUTELY NO WARRANTY.
