New nabu-multicor app fails with `AttributeError: 'CudaChunkedPipeline' object has no attribute 'sino_builder'`

Launching nabu-multicor ../bamboo_hercules/nabu.conf 2050:2070:1 --slice middle fails with the following error: with

Traceback (most recent call last):
  File "/home/lesaint/envs/tomotools/bin/nabu-multicor", line 8, in <module>
    sys.exit(main())
  File "/home/lesaint/envs/tomotools/lib/python3.9/site-packages/nabu/app/multicor.py", line 59, in main
    sino = pipeline.sino_builder.get_sino(pipeline._d_radios, 0)
AttributeError: 'CudaChunkedPipeline' object has no attribute 'sino_builder'

Setting the force_use_grouped_pipeline does not fix the problem.
