Pairing with bluetooth devices not working on 15.04

[janot]

Devices paired on 14.10 are working normally but I'm not able to pair with any new device

1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu
15.04
3) What you expected to happen
Window with pairing key and confirmation button should appear
4) What happened instead
It doesn't appear
e.g: when trying to pair from Windows PC there is window with PIN and "Confirm" button, but it doesn't appear on Ubuntu. When I click "Confirm" on WIndows PC it shows pairing error.
(Similar things happen when trying to pair with Android phone and etc.)
