TIFF to PCL Conversion still broken

[GeneralHQ]

I have a TIFF image, but when I use ImageMagick to convert it to a PCL file, the resultant output file is all black.

convert image-1.tiff image-1.pcl

The same thing happens in my code, when I load in the TIFF image and execute the command:

tiffimg.magick( "PCL" ) ;

No errors or warnings are given, it just does not produce usable output.
I'm using ImageMagick Version 6.6.6-10
(I know this used to work with Version 6.4.3)

Post a URL to your image so we can download and reproduce the problem. We need to trace the source of the problem before we can comment.

I don't have a URL with the image, but I just e-mailed it to:
generalHQ@studio.imagemagick.org

We have a patch in ImageMagick 6.6.7-2 Beta available by sometime tomorrow to fix the PCL problem you reported. Thanks.
