When I click on the Dock icon, then both of them show up. Here's a link to the entire project and a build that does not work: https://cloud.box.com/s/tuzakq025ab7t49geoh9

No, argv_emulation should work fine. However: it is also not very useful for applications that use PyObjC.

Argv_emulation is a hack for using cross-platform scripts: it starts a temporary eventloop to intercept file-open events, adds those files to sys.argv and finally starts the actual script. With PyObjC you can use the regular Cocoa mechanism for this (such as the application:openFiles: selector on the application delegate).
