After today's (1-May) update, these do not work:
xorg-x11-server-common-1.15.99.902-5.20140428.fc21.x86_64

File the bug or wait it out? Everything looks normal in /var/log/Xorg.0.log (with today's updates) until the backtrace appears:

After an install with Anaconda 21.34-1 first resulted in a system that would not go into X and a second install resulted in a broken boot,
I reverted to a Fedora 20 anaconda and installed an Xfce system
with development tools.  This system is working.

BTW I force installed libgcrypt from Fedora 20 and was able to get
Chromium to install and run.
