Ah, now I see were the problem is. In fact, I did not configure anything. Probably, It was messed up during the update process. In preferred applications I had "Custom" selected without a command. It would have been nice, if Ubuntu could point me directly to the problem or suggest to check these settings.
Problem solved.
