openSUSE Tumbleweed version 20220706


Non-root users cannot start Firefox or virt-manager (other applications may
also be affected) because the file permissions of

/usr/share/glib-2.0/schemas/gschemas.compiled

are 0600.

Changing these permissions to 0644 solves the problem.

This error has been occurring for a few weeks (sorry I can't be more specific).

But the problem occurs again after running zypper up - not in every case, but 
occasionally. I could not yet find out which package upgrade causes the
problem.

Thanks
