Shell page apparently is broken by Chrome 0.49:

shellPage.js.src.js:24932 Uncaught TypeError: Proxy.create is not a function
...

Reproduced on Linux, against OrionHub.

The failing code is in org.eclipse.orion.client.ui\web\gcli\util\l10n.js:

> exports.propertyLookup = Proxy.create({
                                 ^^^^^^

Mark, is there a way by this.  The thing is undefined so we could check for it but could the code continue and do something useful?  (didn't look into it)

Apparently that provisional API was removed and replaced by a standardized Proxy object, which seems to use a vanilla constructor (note args were swapped):

Thanks Rafael -- I've patched the offending source to work around the problem.

This is 3rd party code, and patching is not where we want to be. We should open a CQ for a newer version of GCLI.
