Not sure when this started exactly but I think it started when autobahn updated from 0.10.x

Hi Greg, 

there have been quite a few changes & cleanup around unicode strings recently with Crossbar.io & AutobahnPython (part of supporting more features on Python 3).

Could you try with the latest releases of both and see whether this problem still persists?

Regards,

Alex

This error still exists on 0.12.1 of crossbar and autobahn using python 2.7.11

[Alexander Gödde]

OK, handed this off to hawkowl to take a look at. She should be getting back to you soon.

Hi Greg,

internal handling of unicode/bytes has gotten much more strict (
formerly, we did some "auto coercing" of bytes to unicode).

Could you try with trunk again, since I just committed a (I believe) fix
for your issue:

https://github.com/crossbario/autobahn-python/commit/69b0517a8e0adec60fb1784446c8aae91dd45be0

(I think the trigger might be a client closing the WebSocket connection
with a reason that is Unicode)

Cheers,
/Tobias

forgot: pls retry with AutobahnPython trunk that is .. Crossbar.io isn't the bad guy here ..
