This happens also to me with latest version of eng.traineddata. For me downloading and replacing with older version of it fixed the issue. You can try to use older version of this file from here https://github.com/tesseract-ocr/tessdata/blob/3.04.00/eng.traineddata with: wget https://github.com/tesseract-ocr/tessdata/raw/3.04.00/eng.traineddata and save it in your tessdata folder (ex. /usr/share/tessdata)

@kkaczmarczyk Yup, that same worked for me very long back. I didn't updated that information here

Thank you for bumping, marking it as close.
