Hi bug reporter and hi assignee and others involved,

Please reopen this bug report if it is still valid for Mageia 8 or 9(cauldron), and change "Version:" in the upper left of this report accordingly.

This report is being closed as OLD because it was filed against Mageia 7, for which  support ended on June 30th 2021.

Thanks,
Marja
