Tethering via bluetooth is not working (no IPv4)

[Lorenzo]

I'm trying to share a connection from my phone to the laptop. After setting up the phone and pairing the two devices, connecting to the network using blueman ("Bluetooth Devices" window) is impossible, as an IPv4 is never requested. Right clicking on the phone icon and forcing an address renew results in a crash. The only way to get it working is to open a terminal and issue "sudo dhclient bnep0".
