panic on api status: GET /v1

[fopina]

After upgrading my existing cluster to 3.0.5, nodes panic when GET /v1 is issued (used by my healthcheck script).

I haven't been able to reproduce it in a clean cluster, but it always happens in my existing one.
I upgraded from 3.0.2 and it broke. Downgraded to 3.0.4 and it works.
It'd seem to be related with 7de2275
