[SyneRBI/SIRF] Partitioner crashes kernel (Issue #1379)

[Vaggelis Papoutsellis]

epapoutsellis created an issue (SyneRBI/SIRF#1379)

When I am trying to partition the petric data using docker petric2 (local is mac-arm) my kernel crashes.

It crashes inside the partitioner.data_partition, at this line: https://github.com/SyneRBI/SIRF-Contribs/blob/d62593f98c966b601f660808247a682757f80e3c/src/Python/sirf/contrib/partitioner/partitioner.py#L156
