Ocrfeeder seems broken (missing patches for current python version?)

Hi, trying to use ocrfeeder, I am getting:

Traceback (most recent call last):
  File "/usr/lib/python3.9/site-packages/ocrfeeder/studio/widgetModeler.py", line 580, in __performRecognitionForPageFinishedCb
  File "/usr/lib/python3.9/site-packages/ocrfeeder/studio/widgetModeler.py", line 474, in __updateImageReviewers
  File "/usr/lib/python3.9/site-packages/ocrfeeder/studio/widgetModeler.py", line 233, in updatePageData
    for data_box in self.page.data_boxes:
TypeError: 'NoneType' object is not iterable

Is this due to some missing dependency or, more likely, to something needing updates for the python version available on Manjaro?

Hi, Sergio, are you running on stable?
What do you get from the commands bellow?

python --version
echo "PythonPATH: $PYTHONPATH"
ls -d /usr/lib/python*

Hi, yes running on stable, Python 3.9.9. No specific PYTHONPATH set, /usr/lib/python2.7 and /usr/lib/python3.9.

Another potential reason for the problem, in fact more likely, is that I am already on tesseract 5.

Python 3.10.1 is just around the corner. Soon it will arrive at stable.
