I just upgraded my machine to all current devel packages yesterday. Now "xclock -digital", instead of displaying the current time/date, displays the number "20" in a small square. Not terribly useful.
It is believed that this problem was caused due to transient issues with app-defaults that are no longer present in the current development packages. Please update to the latest fedora devel packages, and indicate if the problem is resolved or still present. Thanks in advance.
Problem is gone in current devel packages.
