A key doesn't get imported from one of the keyservers

[Yuri Kanivetsky]

Hi,

The following two commands succeed:

$ gpg --keyserver keyserver.ubuntu.com --recv-keys
409B6B1796C275462A1703113804BB82D39DC0E3
$ gpg --keyserver hkp://pgp.mit.edu --recv-keys
409B6B1796C275462A1703113804BB82D39DC0E3  # sometimes

But this one doesn't:

$ gpg --keyserver keys.openpgp.org --recv-keys
409B6B1796C275462A1703113804BB82D39DC0E3
gpg: key 3804BB82D39DC0E3: no user ID
gpg: Total number processed: 1

Is something wrong with the key that resides on keys.openpgp.org? Are
the keys that are one these 3 keyservers the same?

Regards,
Yuri
