They are broken. They specify "Disposal Method" (called refmode in
MPlayer) as 0, about which the specification says:
> 0 -   No disposal specified. The decoder is not required to take any action.

Which is exactly what MPlayer does. The gif instead expect it to behave
like
> 1 -   Do not dispose. The graphic is to be left in place.

Incidentially, the browsers behave the same for both.
I guess I'll commit a hack to fix it anyway though.

Now about the last non-working one:

This does not work in konqueror and does not animate (AFAICT) in
firefox, so it probably is quite broken...
