Use method that actually gets the path
I was trying out the Python plugin and had an issue with building eggs. Apparently, the plugin is trying to set the working directory to the string representation of a FileObject (which is not the same as a path). Using the proper FileObject method getPath() solves the issue. Patch attached.
