Problems relating xfsettingsd and fontconfig on Fedora 29

After upgrading from Fedora 28 to Fedora 29, I noticed a problem with xfsettingsd.

It will lock up the system every five seconds or so, for about one second. This happens right after logging in. A quick remedy is to kill xfsettingsd. Running xfsettingsd again, it seems things are alright, until I open a terminal emulator, then the problem starts anew, and necessitates killing xfsettingsd.

Originally, I thought this was related to terminal emulators or vte3, but it turns out this is a fontconfig issue, most likely.

Other people have apparently been hit with the problem, using a different distro, so it's not purely Fedora related: https://forums.kali.org/showthread.php?42495-xfsettingsd(xfce4-settings)-cause-the-pc-freeze-every-two-or-three-seconds

There is a reference to this commit: 5f12f564

Is that the solution to that issue, and I should simply wait for an update, or is there something I can or must do, to alleviate the problem?

Unfortunately, I can't find any error messages to narrow the problem down, if there is a way for me to provide further information, please tell me so.

Thanks, --pb
