I have seen similar segmentation fault error messages, but not by right-click, open GE. It seems to occur after a volume change, select FORCE and Build Node. It doesn't occur repeatedly. Once dumped, the volume can be opened, FORCED and Build Node without issue. In my case, a segmentation fault only occurs during full compilation of a root volume and only on occasion. I suspect my errors are likely caused by experimentation with "creative" object structures?
