Issue running SIBR Viewer #50

Hi,

I trained a scene using this codebase, training ran fine. point clouds, cameras, etc are all valid.

When i run 

SIBR_viewers/install/bin/SIBR_gaussianHierarchyViewer_app \
    --path ${DATASET_DIR}/camera_calibration/aligned \
    --scaffold ${DATASET_DIR}/output/scaffold/point_cloud/iteration_30000 \
    --model-path ${DATASET_DIR}/output/merged.hier \
    --images-path ${DATASET_DIR}/camera_calibration/rectified/images

to view the scene, my SIBR viewer crashes here:

This is especially strange since i have:

1) trained and viewed other scenes using this codebase, all captured via the same method, cameras, etc 2) exported the scaffold and chunk pointclouds + cameras.json to other viewers such as antimatter. The scene itself looks fine.

Any assistance with this is appreciated
