#1 Publishing broken in Mac OS X v10.7

[Jared Frisby]

I've found that publishing does not work in Mac OS X Lion (verified on two systems running 10.7.2). I tested publishing to iBooks and ePub 2.0.1, both through the menu bar icon and the File menu. The save dialog appears as expected, but no file is created. This problem does not exhibit itself on Snow Leopard.
