Different fingerprints on different servers - general problem?

[Albert]

Sorry, for spam reasons, I am not willing to make the email-adresses 
public, but I found out, that http://www.keyserver.net reports 
other fingerprints than sks-servers, if a RSA-key was created first 
and an El-Gamal-subkey was added. It could be also, that it happens 
only if the key is larger than 1024. In this case a RSA key of 2048 
was created and an El-Gamal-key of 4096. If it makes sense to use 
such large keys is another question.

SKS-servers show the same fingeprint than locally, so IMO 
keyserver.net is a bad choice for checking fingerprints.
