Description of problem:
Doing a Mageia 7->8 upgrade:
 https://bugs.mageia.org/show_bug.cgi?id=28042#c10
there are several occurrences of:

"Error parsing key “help” in schema “org.gnome.settings-daemon.plugins.media-keys” as specified in override file “/usr/share/glib-2.0/schemas/glib2-branding.gschema.override”: 0-10:can not parse as value of type 'as'. Ignoring override for this key."

which always occur in pairs. From the referenced [URL] install log, they occurred after these packages:
 removing upgraded package lib64gnome-autoar0_0-0.2.3-2.mga7.x86_64
 removing upgraded package gnome-system-monitor-3.32.1-2.mga7.x86_64

I think I saw similar things in my own large but otherwise successful test upgrade.
This does not have any apparent unsavoury consequence; but may have (hidden).
It is disconcerting to see if nothing else.

I got the SRPM from:
 $ urpmf /usr/share/glib-2.0/schemas/glib2-branding.gschema.override
 mageia-theme:/usr/share/glib-2.0/schemas/glib2-branding.gschema.override

Version-Release number of selected component (if applicable):
Mageia 7-8 upgrade as of this date

How reproducible:
Presumably every time, but it is not something to repeat.

Steps to Reproduce:
1. Do a Mageia 7 - 8 upgrade
2. Search the install log for 'Error'.

Assigning initially to Donald alias shultz for the SRPM; but it may be down to the different packages noted explicitly.
