Odd error on Rawhide KDE live compose: dependency issue between mariadb-server and systemd-units

[Adam Williamson]

We're getting an odd error when trying to compose KDE live images from
Rawhide:

Error creating Live CD : Dependency check failed : (('mariadb-server',
'1:5.5.31', '6.fc20'), ('systemd-units', ''), 0, 0, None)

There's a bug in livecd-creator which causes the nightly composes to hit
a traceback instead of printing out the actual dependency error, but if
you apply the fix for the livecd-creator bug, this turns out to be the
actual dependency error that's being hit.

So...clearly it thinks there's a problem with mariadb-server's
requirement of systemd-units . But systemd provides systemd-units , and
systemd is in the downloaded package set, and presumably planned to be
installed. So anyone have any idea why this would be happening?
