Maximum recursion depth exceeded with JSON on web2py

[pyjsorg]

Before reporting a problem, please UPDATE TO LATEST SVN.
As this is a community-driven project, the developers only
have time available to fix problems reported in the LATEST
code. You are welcome to report problems in any other
version, but until you have upgraded to latest svn and provided
a test report against that, you will be reliant on people
OTHER than the core developers for bug-fixes. which could
happen, so feel free to ignore the above should you so choose.

What steps will reproduce the problem?
1.Import attached w2p appliance in latest web2py
2.Try typing in debug page AutoCompleteTextBox

What is the expected output? What do you see instead?
Expected output is the population of the AutoCompleteTextBox with list taken from the JSON responce. Instead i get the following errors :

Please provide any additional information below.
The service is fully functional since the following simple code works like a charm,

import jsonrpclib
server = jsonrpclib.Server('http://localhost:8000/debug/default/call/jsonrpc')
for item in server.getDescription('canon'):
print item

that code returns as it should
