This key has a zero-length User ID. that is, the User ID is the empty
string ("").
You can see this with:

i suppose someone could argue that a zero-length user ID is valid, but i
don't see any use for it, and i can imagine it causing problems in a lot
of situations. So i think on balance i'm that gpg rejecting it by
default is doing the right thing.
