Sorry, but the only way I could repeat your problem was by entering the wrong passphrase for the key when asked. Loading the key into the authentication agent (gpg-agent) didn't lock it in any way (it wasn't even opened, checked with lsof).

Hi all,

hm, well, now that's interesting: I have generated a new key, and now I can unlock it with my passphrase on the office system...
So, I will replace my key, and I think this will solve the problem. But, why can I use the passphrase to unlock the key when the Gnome agent asks for it??

Nevertheless, I think we can close this thread, :-).

Thanks to all who answered, and kind regards from Germany,
