+++ This bug was initially created as a clone of Bug #420591 +++

Description of problem:
When creating a new cron job with kcron, there's a checkbox to make the job
silent.  If you enable the silent option, kcron fails with a generic error:
  An error occurred while updating crontab.

Launch kcron from a terminal and this error appears when saving the job:
  "/tmp/kde-user/kcrondR2FDb.tmp":2: bad minute
  errors in crontab file, can't install.

The problem is that kcron tries to insert a '-' before the minutes field to make
the job silent (apparently this is an extension for some flavors of cron). 
I.E., the line it creates looks like
  -1 2 3 4 5 /usr/bin/something

This has been reported upstream and the silent option has been removed.

upstream patch to remove silent option from kcron

I've tested this patch on RHEL 5.1 and verified it removes the Silent option.

It also removes any offending leading '-' characters from legacy silent jobs.
