Platform: 9086.0.0 (Official Build) dev-channel veyron_mighty

Steps to reproduce the problem:
1. "Share" the Chromebook via Chrome Remote Desktop
2. "Access" from another machine by entering the code
3. "Accept" connection on 

What is the expected behavior?
The guest connects to the host, a remote session is shown.

What went wrong?
"The access code is invalid. Please try again." shown on the guest system. Trying to "access" the Chrome OS system again crashes the host, but no crash report is generated. Cancelling on the client side results in an empty error message with a warning symbol.

Crashed report ID: No crash report shown there

How much crashed? Whole browser

Is it a problem with a plugin? Yes Chrome Remote Desktop

Did this work before? N/A 

Chrome version: 57.0.2951.0  Channel: dev
OS Version: 9086.0.0
Flash Version: Shockwave Flash 24.0 r0

I have tried connecting between two Chromebooks on different channels (stable/beta/dev) and a Ubuntu system. The only combination not resulting in a connection failure/crash is the one with the Ubuntu system acting as host.
