Description Oliver Klee 2005-04-30 13:31:59 UTC
Version:           1.2 (using KDE KDE 3.3.2)
Installed from:    Debian testing/unstable Packages

Steps to reproduce:
1. Right-click on a key that has no missing signatures.
2. Have a look at the context menu.

Expected result:
The menu item "Import missing signatures from key server" is disabled.

Actual result:
The menu item "Import missing signatures from key server" is enabled. Clicking on it pops up an alert saying that all signatures are already in the key ring.

This should be changed following the usability principle: "Disable all GUI elements that don't lead to an action (e.g. Paste when the clipboard is empty)."

SVN commit 705127 by dakon:

Deactivate "import missing signatures" when we already know to have all

Be careful: we don't "know" if the key has never been expanded before. Only 
key expansion loads all the signatures and will take several seconds on a 
big keyring. Therefore unexpanded keys will lead the item always to be visible 
(behaviour like before).
