In the address book, click on a user defined group, then right click on of the entries in that group. One of the menu item is labeled "Delete". Selecting that entry has the following effects: 1. the entry is removed from the group. It is *not* deleted from the address book. 2. the email address defined inside the entry is deleted (other fields, like name(s) and "other attributes" don't seem to be affected). Which is obviously not what this menu item is supposed to do. This menu item should either completely delete the entry - that's what the name suggests, after all. But in that case there should be a requester asking for confirmation, like when selecting "delete" on an entry in normal view. Or this menu item is supposed to remove this entry from the current group. In that case, the menu entry should be renamed to reflect this, and the process shouldn't remove the mail address from the entry.
