Bug 58458 – KMail 1.6.82 complains that it can find no backends for key listing while configuring PGP

• Product: Gentoo Linux
• Status: RESOLVED WORKSFORME

[Description Jason Ahrens 2004-07-26 12:32:56 UTC]

While configuring PHP Cryptography for KMail 1.6.82, it complains that "No backends found for listing keys. Check your installation."

I did build kdepim with crypt USE flag.

Reproducible: Always
Steps to Reproduce:
1. On any user identity, click Modify
2. Go to Cryptography tab, and click Change for either the GPG Signing key or GPG Encrypting key.

Actual Results:  
Error appeared "No backends found for listing keys. Check your installation."

Expected Results:  
A list of available keys from GPG should have been displayed.

I seem to have had a fat finger. That should have been GPG Cryptography. That's what I get for working on web servers all day before reporting a bug.

[Comment 2 Gregorio Guidi (RETIRED) 2004-07-27 10:05:26 UTC]

What do you have in
KMail configuration -> security -> crypto backends ?

also, what version of gnupg and gpgme have you installed?

[Comment 3 Jason Ahrens 2004-07-27 17:53:23 UTC]

In that window I have several selections:
OpenPGP (gpg)
S/Mime (faied) (greyed out)
OpenPGP (Kpgp/pgp2)
OpenPGP (Kpgp/pgp5)
OpenPGP (Kpgp/pgp6)
OpenPGP (Kpgp/pgp1)

I tried using all of these. Tonight it worked once, but then stopped working again. Unfortunately I do not know what was different that "once".

I tried something else today. A trick that worked when I upgraded from 3.1 to 3.2 for the issues I was having.

I moved the ~/.kde3.2 and ~/.kde3.3 directories out of the way, thereby forcing KDE to remake them. All of the problems and instabilities I was having have cleared up so far. This is more a workaround for this problem, but I imagine the ultimate source would be something the kmail people would have to find and fix, as it's apparently not a system configuration issue.

[Comment 5 Gregorio Guidi (RETIRED) 2004-07-29 16:55:14 UTC]

It seems the situation of cryptography support in kmail is in a transition phase, work in progress in bug 58640 and by the kde/gpgme devs

you were unlucky to came in in the wrong moment ;)

[Comment 6 Caleb Tennis (RETIRED) 2004-09-02 14:30:55 UTC]

this seems to work for me now with gnupg 1.2.4 and a re-emerge of kdepim.

[Comment 7 Gregorio Guidi (RETIRED) 2005-01-18 10:39:00 UTC]

The issues with kmail/gpgme should be resolved now. Closing.
