Dear Maintainer,

Hello,, while preparing the new silx package, I got this error message from sphinx when calling this command line

	# build man pages

This is because sphinx-panels defines the handler for "fontawesome" role for
manpage builder as (None, None):

https://sources.debian.org/src/sphinx-panels/0.6.0-3/sphinx_panels/icons.py/#L144

While Sphinx expects at least the visit function (the first pair element) to
be not None.

However, sphinx-panels is dead, and upstream recommends to use sphinx-design
instead. And in sphinx-design this bug is fixed:

https://sources.debian.org/src/sphinx-design/0.5.0-2/sphinx_design/icons.py/#L42

https://github.com/executablebooks/sphinx-design/pull/88

If you want a fix in sphinx-panels, please reassign the bug. Otherwise, if you
have found another solution, please close it.
