I realize this is a dependency of the DeDRM plugin, not calibre itself, but I imagine most Gentoo users with calibre also use this plugin.

Looking at calibre's debug mode logs, I think the error is: Recently, app-text/calibre, with the DeDRM plugin installed, has failed to remove DRM when importing purchased ebooks.
