PyObjC

Between py2app 0.3.2 and 0.3.4, building plugins that load broke. I've
included a demo of the problem as an Xcode project. Building and
running the command line tool target will build the plugin as well.
The command line tool simply attempts to load the plugin. (you may
have to copy the built plugin bundle to the products directory or
change the path to the plugin in the project's products list.

Loading the plugin fails at -[NSBundle load] if py2app > 0.3.2 is used.
