Hi,

I'm running cutadapt (from TS) on a collection with 96 datasets, started from a workflow as an intermediate step.

About half of them fail with this message.

Traceback (most recent call last):
  File "/mnt/galaxy/galaxy-app/lib/galaxy/jobs/runners/__init__.py", line 590, in finish_job
    job_state.job_wrapper.finish( stdout, stderr, exit_code )
  File "/mnt/galaxy/galaxy-app/lib/galaxy/jobs/__init__.py", line 1261, in finish
    ActionBox.execute(self.app, self.sa_session, pja.post_job_action, job)
  File "/mnt/galaxy/galaxy-app/lib/galaxy/jobs/actions/post.py", line 532, in execute
    ActionBox.actions[pja.action_type].execute(app, sa_session, pja, job, replacement_dict)
  File "/mnt/galaxy/galaxy-app/lib/galaxy/jobs/actions/post.py", line 405, in execute

AttributeError: 'NoneType' object has no attribute 'input_datasets'

Running release 15.07 rev cf29f6c4a7

Is that Known? How to avoid?

Best,

Alexander
