I don't know for 2.5.xx  but for 2.4.xx in order to use RFCOMM protocol 
you must use a SOCK_STREAM and not SOCK_RAW socket type.
(SOCK_RAW is for HCI , SOCK_SEQPACKET & SOCK_DGRAM for L2cap)
I think it must return an error instead of making a segfault, in this 
way it is a bug.


Regards

Aurelien
