gpg -kv 'Roland Rosenfeld'

gives me the following output:

As you can see, all keys are displayed twice. IMHO this isn't
correct...
But I don't know, whether the keys (the same seems to happen to _all_
keys in my pubring) are stored twice in the pubring or only displayed
twice.

Here's my options file:

force-v3-sigs
compress-algo 1
keyring gnupg-gdbm:pubring.gpg
load-extension rsa
load-extension idea

Maybe the problem has to do with the gdbm-pubring?


Another question: Is there any chance to import a gdbm keyring? When
having problems before, I used to move the old pubring to bak, created 
a new one and imported the backup. This doesn't seem to work with a
gdbm keyring, instead of this I get the following message:

gpg: no valid RFC1991 or OpenPGP data found.
gpg: Total number processed: 0

Ciao
