Total size reported incorrectly to be -1

The actual responses: https://gist.github.com/ayllon/96b2f8294ae0890f9e802a2bcadaff2e
The output (for instance)

[

{ "spacetoken": "10000", "owner": "VoGroup=\/atlas VoRole=production", "totalsize": -1, "unusedsize": 559919461289477, "usedsize": 0, "guaranteedsize": 11221615673081856, "lifetimeleft": -1, "retention": "REPLICA", "accesslatency": "ONLINE" }

]

That total size looks like an overflow somewhere. Not sure where along the pipe, may be srm, or may be gfal2.
