The reason for this is that a .gpg or .asc file can contain multiple plaintext and signature streams and the handling of this stream is only possible when correctly following the gpg state.
The gpg "--verify" option has been changed to be way more strict than before and fail on files with multiple signatures/blocks to mitigate the problem of doing --verify and then -o extraction.
This problem could be used by an attacker to remotely execute code by using handcrafted YaST Online Patch files put onto a compromised YOU mirror server and waiting for the user to run YOU.
This problem is tracked by the Mitre CVE ID CVE-2006-0049.
