Hi Luiz,

We have done some implementation for AVRCP 1.6 feature GetTotalNUmItems, for
which we are setting up complete testing setup for AVRCP.

As CT side, on linux box,
1. bluetoothd up and running 
2. Registered endpoint with test/simple-endpoint 
3. Running bluetoothctl with agent registered as default agent 
4. bluetooth player is also running and waiting for list of available player

On TG side, PTS test suite, triggered below related test cases, 
TC_CT_MCN_NP_BV_10_C 
or TC_CT_MCN_CB_BV_12_C 

We got the AVDTP channels connected, AVCTP connected, and PTS is waiting for
command set browsed player to select the player  

on CT side, bluez, before calling set_browsed player, bluetoothd exits
abnormally. I could not find it why is it so. 
captured bluetoothd logs;

Any clue on this? Is there anything we missed in AVRCP setup?

Thanks
