Bluetooth blueman DBusFailedError

There was error connecting bluetooth headphones in Ubuntu (xfce) 16.04 : "Connection Failed: blueman.bluez.errors.DBusFailedError: Protocol not available".

One of the solutions is installing bluetooth module for pulseaudio

1) sudo apt-get install pulseaudio-module-bluetooth
2) pactl load-module module-bluetooth-discover

or

sudo service pulseaudio restart

or

pkill pulseaudio

3) Remove device from the list and try to pair it again.

blueman d-bus error

File transfer was not working from laptop to smartphone and vice versa. Devices connected to each other without problems.

There is a plugin TransferService in Plugins section. When I've tried to wnable it the message with error was shown:

BSOD 0x00000074 BAD_SYSTEM_CONFIG_INFO

STOP 0X00000074 (0X0000000000000002, 0XFFFFF88002E22B20, 0X0000000000000002, 0XFFFFFFFFC000009A)

If you get BSOD STOP 0X00000074 error on Windows booting,  you must to boot from bootable Windows DVD installation disc.
Run bcdedit commnad from Recovery console and type next commands.

bcdedit /deletevalue {default} numproc
bcdedit /deletevalue {default} truncatememory

Those commands would change quantity of processors and maximum memory option.
