Using Kinect v2 and and Leap Motion together

I am trying to use both Leap motion camera and Kinect v2 together for a project. I am using pykinect2 and leap motion python library. I have created separate projects and algorithms for each and they are working perfectly fine. But when I try combining them, I am getting error

> The program '[12456] python.exe' has exited with code -1073741819 (0xc0000005) 'Access violation'.

The frame work of my code is shown below:

class Kinect(object):
 def method1(self):
    .....
 def method2(self):
  ......
 def method3 (self):
    if condition1 ==true
        switch_leap()

class LeapListener(Leap.Listener):
 def method1(self):
  .....
 def method2(self):
 .....
 def method3(self):
 .....


def switch_leap():
    # Create a sample listener and controller
    listener = LeapListener()
    controller = Leap.Controller()

    # Have the sample listener receive events from the controller
    controller.add_listener(listener)   

__main__ = "Kinect v2 Body Game"
print("yooooo")
paikinect = Kinect();
paikinect.method3();

The program exits itself with the fore mentioned error as soon as the condition to switch to leap is met. I am trying to figure this out, but I don't know where to start or where to look. Will this work if I use Unity? Any ideas or suggestions will be greatly appreciated.
