context, timezone json.dumps issue

Bug
What is the current behavior?
If I tried the pywit message function with this context:
{"timezone":"America/Los_Angeles"} - the generated url (because of json.dumps) contains slashes ''. And it seems does not work the timezone calculation for this type of text: call me at 8 (so without AM or PM).

I changed temporary the wit.py line 76. from this:
params['context'] = json.dumps(context)
to this:
params['context'] = context

Maybe I used a wrong format for context. Can you deliver me a better one or explain why with json.dumps(context) make a wrong url request?

Thanks.
