reopen 346182 reassign 346182 libvtk6.2 thanks This bug is still present for the same test file. A gdb backtrace pins it on vtkVRMLImporter::exitField() from /usr/lib/x86_64-linux-gnu/libvtkIOImport-6.2.so.6.2, which is in package libvtk6.2.
It's essentially the same backtrace as before, only coming through libvtkIOImport-6.2.so.6.2 instead of libvtkHybrid.so.5.8 Here is the backtrace for the python execution: $ gdb python GNU gdb (Debian 7.10-1+b1) 7.10 ...
