Weird!

I'd suggest breaking it up into pieces, and investigating each piece.

First, curl the file and make sure you get something that looks like
the key on stdout.

Next, redirect that output to a file and make sure you have a key in
that file.

Then gpg --import that file.

It's the "saved [19665/19665]" part that I find most interesting --
it's as though your version of curl is storing the output to a file
rather than printing it on stdout.

Maybe somewhere out there is a curl that doesn't output the page to
stdout by default?
