@orta this is a bug in stats -- it needs to handle the master repo not being cloned.

I'm not sure, TBH I thought this was a safe assumption on the CP API for checking for the existence of a spec repo, is it not?

Ah you know what, it might be a bug in the SourcesManager. It should return an empty array for master if that repo hasn't been set up.
