tesseract: tesseract --list-langs doesn't print languages installed

Environment

• Tesseract Version:4.0.0-beta.1-370-g8b64
• Platform: Linux Ubuntu 16.04 LTS

Current Behavior:

tesseract --list-langs gives the following error log : read_params_file: parameter not found: enable_new_segsearch

Expected Behavior:

Should give a list of all languages installed.

Any idea what to do? I tried searching previous issues, the closest I came to was #1620 . Also, I’m using a custom digits.traineddata file made from running lstmtraining.
