Comment 3 for bug 419471

Sincs it is an hourly task you have to use crontab, to edit your crontab
manually do:

$ crontab -e

To just list it:
$ crontab -l

In fact, just deleting the data files should make gnome-schedule use
some default values. They are located in ~/.gnome/gnome-schedule/crontab

$ cd ~/.gnome/gnome-schedule/crontab/ && rm *

In case that doesn't work you could delete your entire crontab
(scheduled recurrent tasks) with:

$ crontab -d
