"A server must not mask any frames that it sends to the client" error on Google Chrome 38

[Rafael Peressinoto]

Hi,

Anyone experiencing the folowing error message on Google Chrome latest version (mine is 38.0.2125.101)?

WebSocket connection to 'ws://<host>/ws' failed: A server must not mask any frames that it sends to the client. "

I'm using CherryPy server (v3.2.2) with latest ws4py (0.3.5). 

Issue started after Chrome has upgraded from version 37.

Thanks in advance
