[1.3.13.0] Error when submitting from RenderPassWedge

[vNicolini]

Version: Gaffer 1.3.13.0-windows
Renderer: Arnold

When submitting from a RenderPassWedge node, after the submission completion it throws the following error pop-up:

ERROR   [Dispatch Error] IECore.Exception: Traceback (most recent call last):
  File "G:\pipeline\Utilities\Tools\Gaffer\GafferDeadline\python\GafferDeadline\DeadlineDispatcher.py", line 133, in _doDispatch
    self.__submitDeadlineJob(rootJob, dispatchData)
  File "G:\pipeline\Utilities\Tools\Gaffer\GafferDeadline\python\GafferDeadline\DeadlineDispatcher.py", line 217, in __submitDeadlineJob
    deadlineJob.getTasks()[0].getStartFrame() + 1
TypeError: unsupported operand type(s) for -: 'NoneType' and 'NoneType'

It doesn't seem to impact the dispatching/rendering process to Deadline whatsoever though.

Let me know if you need additional info.

Cheers,
VNI
