Their seems to be a problem with the encoding. My user id also includes an 'ö'. I generated the key with GnuPG. gpg --list-keys gives me "Ingo Klöcker ..." as user id. You could try gpg --list-keys --with-colons. Then the user id is printed in UTF-8 encoding. In UTF-8 the 'ö' becomes 'ö'.

I just tried gpg --with-colons on the key data you included in your messages. This gives me "Peter Knöll ...". So the problem is that PGP saved the 'ö' as 'ö' instead of saving the UTF-8 representation of it. It seems that PGP 7.0 is not RFC2440 compliant. No wonder that GnuPG gets confused when it tries to interpret 'öl' as UTF-8 encoded character. I'm really glad I used a RFC2440 compliant program to generate my OpenPGP keys. Thanks for this great program, Werner!
