works fine for me. I notice that in the reporter's apt-get output, tesseract-ocr version 3.04.00-5 is being installed. 'tesseract -v' however shows a version 3.03 is running, and that is clearly also the engine version in use when no output is produced.
My guess is that Bernhard has a version 3.03 binary of tesseract somewhere in his PATH, which takes priority over the system version but fails to produce output together with version 3.04 language files. Bernhard, what's the output of "which tesseract" on your system? Does the stretch version produce output when called as /usr/bin/tesseract ?
