Can't get ride of cron job installed by iSync/Zimbra PrefPane

[mraible]

I can't seem to figure out how to disable the cron job installed by the Zimbra Pref Pane on OS X. I keep getting system e-mails like the following:

/bin/sh: line 1: /Library/PreferencePanes/Zimbra.prefPane/Contents/Resources/ZimbraHelper: No such file or directory

Any ideas would be great.
