Thanks Kevin, That's almost what I was doing, but I had never managed to progress that far (to the delaunay filter) due to crashes.

I don't know... does this Q&A answer that? http://askubuntu.com/questions/53708/how-to-create-debuginfo-package I've done as suggested in the accepted answer and now the repos offer me the following new packages: paraview-dbgsym - debug symbols for package paraview paraview-dev-dbgsym - debug symbols for package paraview-dev paraview-python-dbgsym - debug symbols for package paraview-python libxdmf2-dbgsym - debug symbols for package libxdmf2 libvtkedge-dbgsym - debug symbols for package libvtkedge Any recommendations for which one(s) I should install, and then next steps?
