I just started using Tesseract.

I am following the instructions described here.

I have created a test image like this:

training/text2image --text=test.txt --outputbase=eng.Arial.exp0 --font='Arial' --fonts_dir=/usr/share/fonts

Now I want to train the Tesseract like follows:

tesseract eng.Arial.exp0.tif eng.Arial.exp0 box.train

Here is the output that I have:

Tesseract Open Source OCR Engine v3.04.00 with Leptonica
Page 1
APPLY_BOXES:
   Boxes read from boxfile:     112
   Found 112 good blobs.
Generated training data for 21 words
Warning in pixReadMemTiff: tiff page 1 not found

This prevents the creation of fontfile.tr file. I have tried continuing by ignoring the warning, but when creating the char-sets I get an awefull content:

unicharset_extractor lang.fontname.exp0.box

"58

u 0 0,255,0,255,0,0,0,0,0,0 NULL 0 0 0  # u [75 ]
..."

Here is the version I am using:

tesseract 3.04.00
 leptonica-1.72
  libjpeg 8d (libjpeg-turbo 1.3.0) : libpng 1.2.50 : libtiff 4.0.3 : zlib 1.2.8

Any idea why this happens?

It may be a bug, I'm using v4.00.00alpha and I get
