It all started after upgrading bluez from 4.69 to 4.76 .
'hcitool scan' work and bluetoothd starts normally, but when launching
any related program (e.g. Gnome bluetooth-applet), bluetoothd dies with segfault:
  Oct 24 11:31:01 IL kernel: bluetoothd[3894]: segfault at 0 ip
  b7632653 sp bfee9b5c error 4 in libc-2.12.1.so[b75be000+145000]

Downgrading to 4.69 helps, I don't even have to reboot, just
restarting bluetoothd

Additional info:
