| System crash using bluetooth |

While doing more tests with multiple threads call to HCI lib functions I got a system crash. Machine halts and need to reboot.
I was using 2 threads at once. first an inquiry then a search service and search name with 2 usb hci device plugged. And after that I was trying an rfcomm connection to the devices.
Kernel version 2.6.19-1.2895.FC6 - bluez libs 3.7.1.
this is an extract from messages.
I know maybe I'm doing something but this seems a bug inside bluez kernel functions.
