start_activity generates run-time error


I tried to launch my application using driver.start_activity() (coded in python). I keep on getting the following error when i run my code:

Traceback (most recent call last):
File “C:\MetroPCS\Automation\NWC_Automation\”, line 98, in
File “C:\MetroPCS\Automation\NWC_Automation\”, line 87, in main
driver.start_activity(‘com.nuance.nmc.sihome.metropcs’, ‘.myMetro’)
File “C:\Python33\lib\site-packages\appium\webdriver\”, line 552, in start_activity
for key in arguments.iterkeys():
AttributeError: ‘dict’ object has no attribute ‘iterkeys’

This looks a defect in the appium python client code. I am using client version 1.3.6 and Appium server

Do you guys know if there is a newer client and appium server I can use that resolves this issue?
