Hi Pablo,
this was probably fixed in release 1.0.6 of the rufus-scheduler gem :
http://github.com/jmettraux/rufus-scheduler/tree/master/CHANGELOG.txt#L31-32http://rubyforge.org/tracker/index.php?func=detail&aid=20476&group_id=4812&atid=18584
You'll find the mailing list for the rufus-stuff at :
http://groups.google.com/group/rufus-ruby
Best regards,
