Add

--with-library=/tmp/empty

I see what you mean, although I don't understand exactly what would be driving those messages. I have been doing a bunch of stuff with custom columns to track where I am at massaging ebook metadata and EPUB formatting. Much of it I have been filling in using Action Chains and template functions. But I'm not sure what it is that would be trying to do anything on launch?

Launching with the empty library works. Do you have a suggestion for what to do after that?
