[ale] encryption question

[drifter]

Still trying to get this netbook up and running at it should.

Kbuntu 10.04 -- fresh install; reloaded files from saved /home.

.gnupg copied back into /home

try to decrypt file and KDE wants to know what application
do I want to use to open the file.  What should happen is a
dialog box should pop up asking for the passphrase.

Obviously I am missing something.
But I don't know what.
Clues would be appreciated as I really needto be able to decrypt
that file.
