OCR-D workflow for slower processors reports errors

I tried to apply the suggested workflow for slower processors. It failed in the last step:

Since I still don't know which step is the culprit, I report the error here.

See more details here.

It looks like these "errors" should be marked as "warnings", because they are not fatal: PAGE XML with text results was created.
