webapp doesn't start on vagrant

i just did an "leap deploy local" and saw that the webapp isn't working.

i have "10.5.5.47 web1" in my /etc/hosts, and https://web1/ gives me (after a cert warning, because the cert is for CN=bitmask.net, not web1):

"We're sorry, but something went wrong."

here's the error log from /srv/leap-webapp/log/production.log

...

Vagrant support isn't on the list for 0.2, but it makes me unsure if it would deploy fine on a fresh, untouched server.
