User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9b4) Gecko/2008031317 Firefox/3.0b4

When I got directly to the following Wikipedia image, it scales to the height of the viewable browser area. However, the image shows in black. If you expand the image it shows the correct image properly. 

Reproducible: Always

Steps to Reproduce:
1. Go to http://upload.wikimedia.org/wikipedia/en/7/75/Talk-page_clutter.png
2. It will display as black. See my screenshot of what I'm seeing. 
3. Expand the image to full size PNG. Image can now be seen. 
Actual Results:  
Images shows in black when in scaled down mode. 

Expected Results:  
Image should be scaled down, but not displaying as a black rectangle. 

I use Ubuntu Linux Hardy Heron beta. This uses Firefox 3.0b4.

This works fine here.

The reason it works on Ria's machine is he runs Windows. :-)
