(I'm the Chromium dev who triaged the bug this morning)
This title is misleading. There's a bug when the SSL handshake for a WebSocket encounters an error, such as an invalid server certificate. This obviously sucks for developers, but for production sites which should not have SSL handshake errors, it should not be an issue.
It's not predictably happening with _all_ websocket server implementations. I tried with node.js using a combination of https and ws modules. That worked. We crashed Chrome using em-websockt and netty, though.
