Not sure where to report this, so here goes... As of just recently, I can't load Nautilus after loading Seaside due to a name clash on "Bindings". It's a global in DynamicBindings-lr.13 (Seaside) and a class variable in Spec-Core-BenjaminVanRyseghem.9 (Nautilus).
Ideally I think DynamicBindings wouldn't be putting a bare word symbol like "Bindings" into globals, but as it happens the declaration in Spec-Core/ComposableModel isn't used and could be removed. Cheers, Martin
