*nod* This happen when submitting first build in project. It somehow fail, but then create the key and next build goes without problem. There is something obviously ordered incorrrectly.
Fixed in commit f0f69ab. Now we create gpg key right after you create project. However the GPG key creation takes some time (e.g. minute) so if you send first build really soon you still hit this behaviour.
