PDFToImage going nuts

Hi,

when I try to convert this PDF

http://www.file-upload.net/download-3624324/test.pdf.html

into images with this command:

java -jar pdfbox-app-1.6.0.jar PDFToImage test.pdf

I get thousands of such warnings:

Sometimes it goes into an endless loop (OK I stop ist after some minutes),
sometime it takes 2 or 3 and creates the images.

What's the problem here?

Thank you.

That issue is solved in the current trunk version, see PDFBOX-479 [1] for
