What was in it previously? I think ~/.local/share/mime/packages is the "source code", and everything else is generated from those. The only files I have in ~/.local/share/mime have come from either Wine associating various Windows-related formats with itself, or the GLib test suite using "application/x-extension-gio-tests" to make sure this is still something that is possible to do. I would guess that the most likely root cause would be some sort of misconfiguration for text/html or a related file type, which might make devhelp misinterpret HTML files as something that it doesn't know how to load? smcv
