Please initialize the pdu-type of multipart SMS before sms assembly
Pulling the pdu-type of the first chunk of a multi-part SMS with 'mm_sms_get_pdu_type' returns a 'MM_SMS_PDU_TYPE_UNKNOWN' instead of 'MM_SMS_PDU_TYPE_DELIVER'.
Please set 'MM_SMS_PDU_TYPE_DELIVER' as soon as the first part is received.
