Carsten extracted this: <div><tt class="rst-docutils literal">str</tt> or <tt class="rst-docutils literal">list</tt> of <tt class="rst-docutils literal">str</tt></div> and it would fail on which came about by a non breaking space (C2 A0) in gbp's source code. Removing these makes gbp's API build pass again but it still looks like a regression in pydoctor. Cheers, -- Guido
