pcd bug

Hello,


probably this bug have yet been pointed out, but i can't find it in 
archives.
With old releases of imagemagick, i had no problem to display or convert 
pcd format with a command line like

$  convert toto.pcd[3] toto.jpg

but with last release (Version: ImageMagick 6.5.1-0 2009-08-27 Q16 
OpenMP), it results in a (really) ugly green picture.
I tried with both linux ubuntu karmic and MSWindow versions of 
ImageMagick, the result is the same green trash color

Moreover, with command line

$ convert toto.pcd[5] toto.jpg
and

$ convert toto.pcd[6] toto.jpg

i have this error message :

convert: Corrupt PCD image, skipping to sync byte `img0001.pcd' @ 
pcd.c/DecodeImage/301

In case bug cannot be fixed, can you indicate me where to find old 
release of ImageMagick ?

Thank you for your help.
