Rt-email-dashboards when query returns blank

Hello, i am using rt-email-dashboards on a cron job to send email to tech
support agents about opened tickets. It works fine, but it also send the
email when the agent doesn’t have tickets opened (meaning, the saved query
returns blank)

I don’t see anything in rt-email-dashboards to avoid this. Perhaps a patch
is needed? I am not a perl programmer but logically the patch should be
simple, something like:

old code:

new code:
if query result is not empty then

end if
