http://code.google.com/p/tesseract-ocr/issues/detail?id=641
What steps will reproduce the problem?
1.Just run with following command:
2./usr/local/bin/tesseract /dir/logo.gif.tif /dir/logo.gif
What is the expected output? What do you see instead?
The file should be converted into text format.
What version of the product are you using? On what operating system?

Can you please provide testing image? I can try it in tesseract from svn.

I can not reproduce problem. I tried it on Windows XP SP3 and it was
without problem. I tried it on Centos 5.7 (I do not have CentOS 6.2) with
tesseract 3.01 and 3.00 and it worked...
So it does not seem to be tesseract problem.
Did you build tesseract by yourself or did you installed it from some
package?
Can you send 'ldd /usr/local/bin/tesseract'?

Yes, I compiled it.

Just to confirm: have you installed the required language data files (which
were updated for v3.01)? I can reproduce this exact error (i.e., a
SEGFAULT in ComputeIntCharNormArray) if the "XXX.traineddata" (and
associated files) aren't present (or aren't readable in the expected
location). The language-specific training files are available from the
downloads page.

Hi,
Thanks, works like a charm after installing the language pack.
Can you please tell me how can I install all the languages pack?

Is you downloaded/used tesseract-3.01.tar.gz, than you have to download all
relevant files manually and install them manually.
Or you can use svn version: install svn and than run:
$ svn checkout http://tesseract-ocr.googlecode.com/svn/trunk/ tesseract-ocr
$ cd tesseract-ocr
and follow instruction in INSTALL.svn[1] But be aware: language data files
are more than 600MB!
