Hi All,

I have a crash in pcm_bluetooth.c when i try a connection.

Here are the details :
I power on my bt headset (Sony Ericsson HBH970) - The headset opens
the connection...
Then i try to play an audio file -> SEG FAULT

at pcm_bluetooth.c:674
674 memcpy(a2dp->buffer + a2dp->count, a2dp-> sbc.data, a2dp->sbc.len);
$

When i launch the player again all is working ==> So this bug appears
only when the
headset is initiating the connection.

My setup:
* Ubuntu / Kernel 2.6.22-6
* This morning bluez-libs and bluez-utils cvs
* pcm_bluetooth.c version : REL-3_18: 1.64

Does anyone have a clue on this issues ?

Regards,

S. Baguet
