delay after error does not work if the job has a run time with a single start

Example:
<job stop_on_error="no">
<script language="shell"><![CDATA[
exit 5
]]></script>
<delay_after_error error_count="1" delay="30"/>
<delay_after_error error_count="2" delay="stop"/>
<run_time>
<period single_start="12:00"/>
</run_time>
</job>

This Job throws an error but it starts on the next day instead in 30 seconds.

The following line is written in the task log:
SCHEDULER-143 Task cannot start because it has no start time and no valid <run_time>
