LSDyna reader crashes on files with RigidBody elements

Some more recent LSDyna files cause a crash in the vtkLSDynaReader when read in ParaView - the call stack is below. Unfortunately the repro data files are private, please contact me if you need them. So far it appears that only files that have RigidBody elements cause a crash. They were likely produced with version: ls-dyna_mpp_d_r9_0_1_109912_x64_redhat54_ifort131_sse2_openmpi183

Rigid body elements might have some assumptions that deflection or other parameters are zero so they are omitted, but this doesn't match the crash call stack.

Recording the issue, but we aren't pursuing a fix at this time.
