Environment:
------------

Linux server 2.6.18-194.26.1.el5 #1 SMP Tue Nov 9 12:54:20 EST 2010 x86_64 x86_64 x86_64 GNU/Linux
CentOS release 5.5 (Final)

Problem:
--------

ImageMagick from the CentOS 5.5 repository:

Name : ImageMagick
Version : 6.2.8.0
Release : 4.el5_5.3
Size : 3.3 M
Repo : updates

appears to have an issue with GIF to PNG conversion. The PNG that is produced as output is "screwed up". I have tried both the i386 and x86_64 package, the result is the same.

Effect:
-------

The original GIF: http://truemetal.org/universe/im-bug/be.gif
# file be.gif
be.gif: GIF image data, version 89a, 32 x 14

The output PNG with ImageMagick 6.2.8.0 from CentOS 5.5: http://truemetal.org/universe/im-bug/re ... -im628.png

The output PNG with ImageMagick 4.2.9 on the same machine: http://truemetal.org/universe/im-bug/re ... -im429.png

The output PNG with ImageMagick 6.6.7-1 RPM from imagemagick.org on the same machine: http://truemetal.org/universe/im-bug/re ... -im667.png

More info from "file" (they're all the same):

# file result-1-by-im628.png
result-1-by-im628.png: PNG image data, 32 x 14, 2-bit colormap, non-interlaced
# file result-2-by-im429.png
result-2-by-im429.png: PNG image data, 32 x 14, 2-bit colormap, non-interlaced
# file result-3-by-im667.png
result-3-by-im667.png: PNG image data, 32 x 14, 2-bit colormap, non-interlaced

How to repeat:
--------------

# /usr/bin/convert -geometry 32x14! be.gif output.png

Workaround:
-----------

Install ImageMagick 6.6.7-1 RPM from the official source:
