Sorry for the late reply, I have not been subscribed to this bug. I have not written earlier because the bug was limited to one location (it seems in connection with one wireless network made available to all users and logging in to the network before logging into the user account), and I wanted to test all cases of old packages, Marcelo's workaround and the new version.
@Marcelo de G. Malheiros: Thanks for your pointer to the packages. Your temporary fix worked well. That enabled me to actually work at this location.
@Guilherme Picooli: Thanks for version "204-5ubuntu20.28". I upgraded to it and it the problem has disappeared.
