Suricata

After an upgrade from the today's git commits (rev e250040) - no rules (rule files) are loaded from suricata.yaml at all.
This ERR is present instead:

(detect.c:411) <Warning> (SigLoadSignatures) -- [ERRCODE: SC_ERR_INVALID_ARGUMENT(13)] - Invalid rule-files configuration section: expected a list of filenames.

However suricata dump config shows that the rule files are specified:

suricata --dump-config -c /etc/suricata/suricata.yaml |grep rule
default-rule-path = /etc/suricata/rules
rule-files = (null)
rule-files.0 = botcc.rules
rule-files.1 = ciarmy.rules
rule-files.2 = compromised.rules
rule-files.3 = drop.rules
rule-files.4 = dshield.rules
rule-files.5 = emerging-activex.rules
rule-files.6 = emerging-attack_response.rules
rule-files.7 = emerging-chat.rules
rule-files.8 = emerging-current_events.rules
rule-files.9 = emerging-dns.rules
rule-files.10 = emerging-dos.rules
rule-files.11 = emerging-exploit.rules
