mftraining: intproto.cpp:602: INT_TEMPLATES_STRUCT* tesseract::Classify::CreateIntTemplates(CLASSES, const UNICHARSET&): Assertion `((IntTemplates)->Class[ClassId] == __null)' failed.

What steps will reproduce the problem?
Feeding in multi character coordinates I guess(not sure because this is the 
first time I am encountering this error).

What is the expected output? What do you see instead?
I expect a done message and generation of the inttemp file.

What version of the product are you using? On what operating system?

I am using Tesseract 3.02 on ubuntu 12.04 lts.

Please provide any additional information below.

I have trained tesseract with my hindi training data and I have named the 
language as hen.
I have made the box files contain the coordinates of simple words instead of 
individual characters to avoid overlapping of boxes. 
I have created the shapeteble using the "shapeclustering" command.
When I proceed to the next step of generating the inttemp using "mftraining" 
the following happens :
/usr/share/tesseract-ocr/tessdata$ mftraining -F font_properties -U unicharset 
-O hen.unicharset hen.lohithindi.exp*.tr

Please help me out.
Thanks

I have attached the unicharset file. I am not able to attach other files due to 
size issues.

You can use some other online service for sharing rest of files - and post here 
just link to them (please zip/rar/... them first)

Hi I have reworked the process and I have all the files required.
The only change is that I have merged all data into a single file.
