Subject: Gracefully exit if no backend defined.
X-Git-Url: https://git.sommitrealweird.co.uk/onak.git/commitdiff_plain/91a98f43c64a6f8c76efb78b8301efaf9c6db1fe?hp=4684b822bc8582622c7ea849aa61665af48a695a

Gracefully exit if no backend defined.
If no backend was defined we were attempting to strlen a NULL string,
which isn't sensible. Gracefully exit with a critical error instead.
