Hello,
I am using the following code in order to perform OCR on an image (attached):

from tesserocr import PyTessBaseAPI
from PIL import Image

DEFAULT_LANGUAGE = "spa"
filePath = "/home/jorge/Desktop/prueba_tess/c1.png"

if __name__ == '__main__':
    img = Image.open(filePath)
    tesseract = PyTessBaseAPI(lang=DEFAULT_LANGUAGE)
    tesseract.SetImage(img)
    tesseract.Recognize()
    print tesseract.GetUTF8Text()
    tesseract.End()

but what I am getting with this particular image in console is the following:
start >= 0 && start + num <= length_:Error:Assert failed:in file ratngs.cpp, line 321

Here is what I am using
tesserocr 2.2.1
tesseract 3.04.01
leptonica-1.71
libjpeg 8d : libpng 1.2.50 : libtiff 4.0.3 : zlib 1.2.8

I think I have all correctly set up because I have extracted text from other images. but with this one throws that "error"...
Any help is appreciated.
Thanks in advance!
