I'm not sure if this is Improved Damage Framework being incompatible with this, but here's a crashlog:

Indeed. Improved Damage Framework has an excessive number of redirects, overwrites, and base level changes, which makes it likely to be incompatible with a large number of mods that it doesn't give explicit compat for. I don't think there's much I can do about that.
