Today they made a new build with Unity 2018.2.

It segfaults.

edit: Removed this comment because it was completely wrong.

Sorry for modifying so much before being sure of what to post.

If you just use a basic scene with the "CameraRig" prefab it works in the preview and in an exported build. If you add the "Status" prefab, the preview works, but an exported build will crash like this.

CChristophHaag 2018-08-03 github

QuiVR devs say they don't use the Status prefab or SteamVR overlays but the QuiVR demo does cause this crash.

It is important for SteamVR on Linux that Valve and/or Unity look into this because 3rd party game developers are still failing at making Linux builds of their games because of issues in closed source components - completely out of their control. If you want SteamVR on Linux to have a chance, issues like this should be of very high priority.
