OpenVR crash in Linux builds

Not exactly sure what is going on here. I've run other OpenVR stuff just fine on this machine. Since it's a crash when parsing a JSON file I wonder if it's a bug in the Linux SteamVR beta or if I'm missing a bindings file or something?

Relevent parts of the stack trace:

Hmm digging around a bit more, it does seem like it might be a SteamVR thing:

All those file exist and are jsonlint says they are valid at least. Not quite sure where to look next... Hmm.

 

Could be your issue same as mine? Are you using recent Unity version 2018.3.0f2?
