python-tesseract not returning same results as command line tesseract #48

What steps will reproduce the problem?
1. Perform OCR on the attached image with command line tesseract (tesseract 
3.png 3 && more 3.txt)
2. Perform OCR on the attached image with python-tesseract
3. Notice the errors thrown from python-tesseract 

What is the expected output? What do you see instead?
On certain images the results I'm seeing from python-tesseract are not exactly 
same as the results from command line tesseract on the same image. 
Additionally, some images (like the one installed) throw errors when 
python-tesseract performs OCR on them. Even though the result is same for this 
image from command line tesseract and python-tesseract. 

In my script this option returns False "print 
"HAVE_LIBLEPT=",tesseract.isLibLept()" I am assuming maybe this is why the 
results are different? 

What version of the product are you using? On what operating system?
$ tesseract --version
tesseract 3.02.02
 leptonica-1.69
  libjpeg 8d : libpng 1.5.14 : libtiff 4.0.3 : zlib 1.2.5

Please provide any additional information below.

I have searched google for this but have not found anything. My question is 
simply that should tesseract.isLibLept() be returning True for python-tesseract 
to return exactly the same results as the command line?

My script is like this:

api = tesseract.TessBaseAPI()
api.SetOutputName("outputName");
print "HAVE_LIBLEPT=",tesseract.isLibLept()
api.Init(".","eng",tesseract.OEM_DEFAULT)
api.SetPageSegMode(tesseract.PSM_AUTO)
