Thanks Austin! I executed the command and now I get:

btrfs qgroup show /
ERROR: can't perform the search - No such file or directory
ERROR: can't list qgroups: No such file or directory

as expected. Now I will wait for +- 1 week to see if the problem will
occur and, if not, I will send an e-mail to openSUSE factory mailing
list to start a discussion if it is better to not enable qgroups by
default.

Best regards and thanks everyone for the help,
