tesseract trained successfully but gives:Tesseract Open Source OCR Engine v3.03 with Leptonica Segmentation fault (core dumped)

[Dovhani Foneworx]

Hi guys, I have a problem, I have succesfully trained tesseract 3.03 in Ubunt 14.04 but when i run tesseract it is giving errors on an image and the image was part of the image.

I have join 4 images with imagemagice and make one big image and when i run tesseract it do the following:

Hi Dovhani,

Does this happen with all images when using your training, or just
one?

Hi Nick, this happens when I test with all images.

In that case it must be a problem with your training data. Can you
let us know the exact commands you used to create it?

Alternatively, you could post a gdb backtrace, if you know how to do
that.
