 Looks like you're using combine as a frame disposal method while you
 need replace. Also note, that GIF cannot handle alpha channel, so you'll
 still end up having aliased contour of the gnome throbber. If you know
 your target background color, you can flatten or semi-flatten prior to
 indexing.

Or use a proper file format for animations such as MNG. GIF is a piece
of crap and should have died a long time ago already.

 True, but it's still widely used and has more support than PNG. It's

 what should be done and what has to be done. In the same way, PNG is
 not as widely and well-supported as it should be, at least in IE.

Sort of true but things will never change if everyone thinks and acts
this way. Only if you web-designers start to write spec-compliant
pages and use the proper formats, only then will the browsers be fixed
to render these pages correctly.

Go a step further.  When you identify a browser that does not support 
current standards (typically, IE), let the user know, either with a 
popup or such.  How many times have you seen similar messages telling 
you, you MUST use IE for a particular website?

Hi,

I want to make an animated gif of the gnome throbber of nautilus. I got 
the original png which contains a rectangle containing the 35 frames. I 
cut these out and put them in a seperate layer in GIMP. If I then play 
the animation in GIMP or save it as an animated GIF and then play it. 
The toes of the gnome foot seem to leave something behind
See:
