I suspect that curl isn't decoding the object because it didn't
send an Accept-Encoding with the request. If you ask it to do so
(add --compress to the command line), then it decodes the object.
I'm not sure where Lars got that URL in the first place, but my
guess is that it's gzipped without an indicator due to a quirk in
how favicons are implemented.

Hope that helps,
