As of 1.7 and later, seems there is an issue loading and displaying animated
gifs.  The URL above always crashed with 1.7.X and later browsers on OS X 10.2 
 OS X 10.3 seems to make the problem less sever, as in the the animated gifs
render bat have weird interlace rendering artifacts.

Reproducible: Always
Steps to Reproduce:
1.
2.
3.



Expected Results:  
Pre 1.7 this never was a problem.

The animated gif was produced using an old Mac OS Classic freeware gif program.
 All other browser have no issue with the format of this animated gif.

Sounds like an OSX gfx issue...

Do you only see this if your display is at thousands of colors?  Does it happen
in millions of colors?
