>Description:
	
As of the upgrade of graphics/ImageMagick to 6.0.x, I can no longer convert
multi-page TIFF images into valid PDFs.  ImageMagick's own "identify"
program cannot decipher them (although it will try to use infinite CPU
and memory in the attempt).
>How-To-Repeat:
	
With ImageMagick 6.0:

    $ convert -version
    Version: ImageMagick 6.0.6 11/29/04 Q16 http://www.imagemagick.org
    Copyright: Copyright (C) 1999-2004 ImageMagick Studio LLC
    
    $ gs --version
    7.07
    $ convert test.tif test.pdf
    $ identify test.pdf
    test.pdf[0] PDF 1056x1375 1056x1375+0+0 PseudoClass 256c 2.8mb 0.031u 0:01
    test.pdf[1] PDF 1056x1375 1056x1375+0+0 PseudoClass 256c 2.8mb 0.023u 0:01

With ImageMagick 6.1.x:

    $ convert -version
    Version: ImageMagick 6.1.9 01/25/05 Q16 http://www.imagemagick.org
    Copyright: Copyright (C) 1999-2005 ImageMagick Studio LLC
    
    $ gs --version
    7.07
    $ convert test.tif test.pdf
    $ file test.pdf
    test.pdf: PDF document, version 1.3
    $ identify test.pdf
    [infinite hang]

I used this sample image:

    http://web2.xrsnet.com/test.tif

ImageMagick 6.0 produced this valid PDF:

ImageMagick 6.1 produced this broken PDF:
