Hi Anthony, thanks for response.
I received an out-list answer too. However that didn't solve the problem.

JPEG format can not save transparency!!!!
Well i was not asking about JPG supporting transparency, but having a
correct mapping into JPG.
I expected something transparent to be mapped into well defined thing.
However i realized now the -background white thing with flattening is
needed.
But the thing is: when i do right that again - no matter how - it's the
same result!
Still pattern in background - you could see the result here:
SRC:
http://www.frankonia-net.ch/imagemagick/M1800R2K8_YAY_2.png
OUT:
http://www.frankonia-net.ch/imagemagick/M1800R2K8_YAY_2.png.jpg
with
$ convert M1800R2K8_YAY_2.png -background white -flatten
M1800R2K8_YAY_2.png.jpg
Experiments show that PNGs >4MB start having such pattern issues.
| This is debian imagemagick:

Also your IM is EXTREMELY old!
Well this is debian sarge - OK conservative, old AND stable... but not
necessarily broken ;-)
Now i have to admit:
On a debian etch 4.01 amd64 this works :-S with
Version: ImageMagick 6.2.4 02/10/07 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2005 ImageMagick Studio LLC
So there was a bug related, solved and not backported.
Unfortunatally there is currently no way of generating new debian
packages and no debian package experts know how to generate such
packages. If we can get the help of a debian expert we could
probably setup the ability to generate of debian type packages.
Looking into etchs imagemagick package, i see
Maintainer: Ryuichi Arafune <[EMAIL PROTECTED]>
Depends: libbz2-1.0, libc6 (>= 2.3.5-1), libfreetype6 (>= 2.2), libice6
(>= 1:1.0.0), libjasper-1.701-1 (>= 1.701.0), libjpeg62, liblcms1 (>=
1.08-1), libmagick9, libpng12-0 (>= 1.2.13-4), libsm6, libtiff4,
libx11-6, libxext6, libxml2 (>= 2.6.27), libxt6, zlib1g (>= 1:1.2.1)
Are those too ancient too? :-S
So primarily i'd contact him for any question about building some more
up-to-date .dpkg
Will you ask him?
The only suggestion I have is to install a personal version of IM for
your system, outside the debian IM package.
Yes, that would be the solution...
Now i changed my sources to TIF (LZW, transparency) from PNG and thing
works - even without flattening and without setting background - out of
the box....
