Unexpected token in JSON at position 0

I'm trying to use the inspector, it works well until I try to inspect a specific view, at which point I always get: `VM365:1 Uncaught SyntaxError: Unexpected token  in JSON at position 0
at JSON.parse ()...`

The inspector goes blank and app falls back to the in-app inspector. The problematic view has some padding expressed as percentages:

```
paddingTop: '20%',
paddingLeft: '14%',
paddingRight: '10%',
```

When I remove them, inspector doesn't crash, when I add them back, it crashes again the moment I select that view in inspector, so it's probably related.
