Doesn't work with robot framework user guide

[patriksevallius]

Running rst2epub.py on RobotFrameworkUserGuide.rst fails

To reproduce:

hg clone https://code.google.com/p/robotframework/ cd robotframework/doc/userguide/src echo ".. |version| replace:: trunk" > version.rst rst2epub.py --traceback RobotFrameworkUserGuide.rst

Still crashes (the project has in meantime moved to https://github.com/robotframework/robotframework.git):

Check #9, I have had this issue because a title is required before any paragraph. EPUB generation seems less flexible than HTML (in its current implementation by this library).
