Tesseract crashes while converting image on win7 machine

[Kristaps]

Can someone please tell me if there is anything wrong with this
particular image?
http://www.mediafire.com/?nol2h4oppycii0p
Ive installed tesseract 3.01 on win7 machine. First i tried to read
phototest.tif from tessdata folder and got result txt file. But when i
am trying to read my a.tif i get "tesseract has stopped working"
message.
The command i am using is: tesseract a.tif aresult -l eng

Any help will be apriciated.

unsupported image type.

On windows only debug version of Leptonica library produces error messages to terminal (e.g. you should build tesseract against debug version of leptonica if you want to see error messages produced by leptonica). Have a look at [1].

On linux I see this:

Tesseract Open Source OCR Engine v3.01 with Leptonica

Error in pixReadFromTiffStream: spp not in set {1,3,4}

Error in pixReadStreamTiff: pix not read

Error in pixReadStream: tiff: no pix returned

Error in pixRead: pix not read

Unsupported image type.

It look like there are problems with either reading tif image with
tesseract or in image conversion process with ImageMagick.
The image is generated from pdf file and is cropped. I changed from
tif to png format and it looks like the problem is solved.
