The font list in the font manager is empty. It does not show the installed fonts. The message "Scanning font list..." never disappears. Reproducible: Always
Works for me. Can you try with a new user account to see if it is related to a bad configuration?
I already did that and it did not resolve the problem. Furthermore, this problem exists since a few updates. I even tried to reinstall my openSUSE Tumbleweed because this bug annoyed me....no change.
It works now since the last update (5.8.2)
We did not change anything, so I assume it was a local or downstream issue. Closing.
