Error installing Rapier out of DEV Repo

Another Bug if you install and activate Rapier out of your Dev Repo from the Addon Manager: The Homescreen will not be loaded.

However i think this is a Kodi internal Problem maybe.
Kodi log says:
19:11:21.255 T:8404 WARNING: CSkinInfo: failed to load skin settings

So maybe there is no default settings.xml?
