Problem: lvr2_reconstruct crashes on some meshes when both --optimizePlanes and --fillHoles are used

LVR version: 20.11.3 (9bb03a3)

System info: Ubuntu 20.04

How to reproduce:

I've attached some test data here: minimal_examle.ply

• lvr2_reconstruct -o minimal_examle.ply: works
• lvr2_reconstruct -f 15 minimal_examle.ply: works
• lvr2_reconstruct -o -f 1 minimal_examle.ply: works
• lvr2_reconstruct -o -f 15 minimal_examle.ply: crashes:

Any luck with this? I seem to have a similar issue any time --optimizePlanes is used. I haven't done as extensive of a job diagnosing the issue as above, but did experience it happening for any mesh (using Ubuntu 18.04 with LVR 20.11.3)
