Bug while importing images larger than 16 MB

Hi Developers,


Recently, while working in an interface
for the command-line bitmap tracing utility, 
Potrace and the bitmap processing utility,
mkBitmap, i found two recurrent bugs that
i want you confirm in your development
environment.

Recipe 1:
import an image that uncompressed
show a size of more than 16.7 MB.

For example, i received this 62k png
that grows to 22 MB when decompressed:
http://www.geocities.com/capellan2000/spoof_eBayMessage.png

When i set the filename of an image object
to this png or any other image, bigguer than 16.7 MB,
the image bleeds off the bounds of the container,
and sometimes redraw itself within other palettes
or stack opened at the moment.

Sometimes, the Developer environment crash...

Is this somehow related to the limit of
4096 x 4096 pixels for an image, in Mac OS X?
Notice, i'm working in Windows, so i thought that
this limitation was Mac OS X only...

By the way, i have posted these screenshots in
my yahoo site for the Potrace Interface.
i'm using the metalic look and interface elements
created by  Chipp Walters for the example stack 
posted in his website:
