I was scrolling the list of fonts in MCC MGA7.1, via Manage system services > Manage, add and remove fonts.
I was only scrolling, so no installing of fonts was being done.
Drakfont segfaulted. The window disappeared, but MCC was still live.

The "drakfont" program has segfaulted with the following error:

FWIW, there are multiple bugs open against drakfont. The most suitable to your issue seems to be https://bugs.mageia.org/show_bug.cgi?id=21829

If you want to view your installed fonts, better use the font viewer from KDE / plasma which is available via systemsettings: https://userbase.kde.org/System_Setting ... Management
