node-inspector: Internal error: illegal access (debugging ES6 proxy)

I’m using node-inspector for node 0.11.13

I start node --debug-brk ..., open node-inspector and enter the code in Chrome. Everything’s fine.

Then I press ‘Continue’ in Chrome and, after some time, in console:

Internal error: illegal access

There is no stack at all.

Is there a way to trace communication with v8 to see at which stage it happened? It looks like a node-inspector bug.
