pairing timeout aborts short after first failed try

After the first try of pairing the Ubuntu notebook with a bluetooth device (phone) failed (phone not ready or pin mistyped), every following try aborts immediately after less than a second (as if the timeout was suddenly shorter). There is no time anymore to read or even transfer the pin.

As a work-around I can reboot and connect with the first try which has a normal several-seconds time-out (but could be longer as well). Of course it would be preferable without the need to reboot.
