Hello,
I was attempting to pair a set of Motorola S9 headphones using bluez 4.7
and received the following crash. Attached is the output of 'bluetoothd -nd'
under gdb, with a bt. I also included the output of
"dbus-monitor --system sender='org.bluez'". I made the following patch and
thought I'm sure it's not the right fix it allowed me to pair/play sound
though the S9.
