The error I get is from our boostrap code:

  Unhandled Error: 'Object.keys' is not a function 
    message "'Object.keys' is not a functio…"
    stack "<anonymous function: keys>([arguments not available])@http://localhost:8080/orion/preferences.js:89
           <anonymous function>([arguments not available])@http://localhost:8080/orion/bootstrap.js:25
           ...

Apparently Object.keys is not supported in Opera 11 (http://kangax.github.com/es5-compat-table/)

That's my bad.

ES5.1 is fully supported in Opera 11.60+ ( beta 11.60 builds available from http://my.opera.com/desktopteam/blog/). There's also Opera Next which is good to test when you run into bugs: opera.com/browser/next/.

11.60 should be out *soon*--if you're using ES5 extensively you might just bump the minimum support version to 11.60 rather than rewrite a ton of code.

Thanks Mike you saved me a bit of time here hunting down links etc.
I had been thinking setting the bar at Opera 12/Next but this build seems to work fairly well. We're consciously trying to avoid using utility libraries and polyfills unless we're truly desperate so... great.

I'm closing this but 11.60+ seems doable and we can open further bugs against the latest Opera 11 as we find them.
