At least part of your problem is the method signature for 
simpleEncrypt_userData_error_. In Objective-C the last argument is a 
pointer to an id. Because not all arguments are an object and your not 
overriding a method from a superclass you'll have to provide a correct 
signature.

In the service I posted earlier I used:

import objc
def NSServiceFunc(meth):
         return objc.selector(meth, signature="v@:@@o^@")

and in class ServiceTest:
	def doFoo_userData_error_(self, pboard, data): # Note: No argument 
error
		# ...
		return (None, None)

	doFoo_userData_error_ = NSServiceFunc(doFoo_userData_error_)

The program still tries to start in the foreground. My example used
'<key>NSBGOnly</key><string>1</string>' in the Info.plist. That didn't 
work here, but at the service is working (using the first alternative 
in __main__.py, and without importing MyAppDelegate).
