Comment # 2 on bug 932789 from Dr. Werner Fink

(In reply to Stefan Br�ns from comment #1)

I've never seen that again. Maybe this is fixed meanwhile.  Accordingly to the
spec file list, also gnome does require for its scheduler cronie:

 man/man.spec:Requires:       cronie
 gnome-schedule/gnome-schedule.spec:BuildRequires:  cronie
 gnome-schedule.spec:Requires:       cronie

Beside this

 rpm -qR cron
 /bin/sh
 cronie = 1.4.11-57.5
 rpmlib(CompressedFileNames) <= 3.0.4-1
 rpmlib(PayloadFilesHavePrefix) <= 4.0-1
 rpmlib(PayloadIsLzma) <= 4.4.6-1

which looks like cron is more like a dummy package:

 cat /usr/share/doc/packages/cron/cron_to_cronie.README
 package cron 4.2 is only auxiliary package needed for proper renaming package
cron to cronie
