Created attachment 1356104 --> https://bugzilla.redhat.com/attachment.cgi?id=1356104&action=edit stacktrace of gnome-shell crash.
Description of problem:
I run Fedora 26 on a Lenovo Thinkpad W541. I ran a "dnf update" last Friday (2017-11-17) and after the update I could not login with any Gnome choice: Gnome, Gnome Classic, or Gnome on X11 - after a couple of burps on the display, it would return to the login prompt. I installed the cinnamon desktop and was able to log in with that.
It turns out that gnome-shell crashes in FcConfigEvaluate - see attached stacktrace.
Version-Release number of selected component (if applicable): fontconfig.x86_64 2.12.6-4.fc26 @updates
How reproducible: Always.
Steps to Reproduce: 1. dnf update 2. reboot 3. login
Actual results: Churn a bit and then return to the login screen.
Expected results: Successful login.
