Home Assistant fails to start up, populates the below errors in the logs. Error doesn't seem to be related to HACS, but my only change on this beta was updating from 0.2.1 and confirmed Home Assistant starts up okay after disabling HACS in configuration.yaml.
To update I initially tried copying 0.4.1 files over 0.2.1, when that didn't work I deleted it all and copied fresh from the repo and had the same thing.
