When my docstring is:
"""First line to briefly introduce the object.
>>> import os
>>> print os
<module 'os' from '/usr/lib/python2.5/os.pyc'>
With no text after the first line but the doctest, Epydoc doesn't link to a detailed description at the end of the page to see the doctest.
I don't know if it's intented. The only workaround to be able to see the doctest in the gnerated doc was to force me to invent a sentence to add after or before the doctest, in addition to the very first line.
