BT (KY-BT100 dongle) worked right after fresh install of Karmic, then I installed blueman from Karmic repositories, and seems that it caused the above problems. Tried to remove blueman completely - did not help. Booting from standard Karmic live CD - BT worked. The problem was solved after installing blueman from PPA, which removed gnome-bluetooth. It worked even before I updated bluez from the same PPA.
When I installed blueman originally from Karmic repositories, it did not remove gnome-bluetooth, and I had two bluetooth icons for some time (both disabled).
