ws4py with CherryPy/cpstats?

[Israel Brewster]

I don't know if this is a CherryPy issue or a ws4py issue, so I'm asking in both places. Please forgive me if that is considered bad form. It it possible to use ws4py in conjunction with the capstans CherryPy tool? I have a CherryPy (3.8.0) web app that uses web sockets via ws4py. Tested and working. I am now trying to get a little more visibility into the functioning of the server, so to that end I enabled the cpstats tool by adding the following line to my '/' configuration:

tools.cpstats.on=True

Unfortunately, as soon as I do that, attempts to connect a web socket start failing with the following traceback:

Disable tools.cpstats.on, and the sockets start working again. Is there some way I can fix this so I can use sockets as well as gather stats from my application? Thanks.
