Looks like syslog-ng passes a wrong type to sys_syslog():

        if (type == SYSLOG_ACTION_OPEN || !from_file) {
                if (dmesg_restrict && !capable(CAP_SYSLOG))
                        goto warn;

                if ((type != SYSLOG_ACTION_READ_ALL &&
                     type != SYSLOG_ACTION_SIZE_BUFFER) &&
                    !capable(CAP_SYSLOG))
                        goto warn;
        }

Hmm, it writes /proc/kmsg... I will look at the code later.
