Description Christian Esken 2004-06-26 12:05:58 UTC
Version:           1.6.82 (using KDE 3.2.90 (3.3 alpha1, CVS >= 20040522), compiled sources)
Compiler:          gcc version 3.3.1 (SuSE Linux)
OS:                Linux (i686) release 2.4.21-99-athlon

I compose a message which works. I do not use encryption or signing for that message.
But as soon as I am finished composing and click "send" a message box appears:

"One or more of your configured OpenPGP encryption keys or S/MIME certificates is not usable for encryption. Please reconfigure your encryption keys and certificates for this identity in the identity configuration dialog.
If you choose to continue, and the keys are needed later on, you will be prompted to specify the keys to use."

I can either continue or cancel that dialog box - the result is the same: KMail crashes.

How to reproduce: Create a fresh ~/.gnupg directory and stick the attached pubring.gpg in it. Run KMail, compose a message and try to send it. The dialog box should appear, then click any of the 2 buttons => crash.

----------------------------------------------
Some extra information (probably not relevant):

Unfortunately I cannot supply a backtrace, as the "KDE Crash handler" does not show up. Also from gdb, I do not get a backtrace, because I get stuck in a "signal SIG43" loop as soon as I enter the composer. :-(

(gdb) run --nofork --nocrashhandler

This isn't enough to get the dialog to appear.
pubring.gpg is unrelated to the dialog, which says "One or more of *your* configured OpenPGP encryption keys".
So it's related to which key you selected in the KMail configuration dialog, for your email identity,
(is there a key selected there?) and it's related to which crypto backend you are using 
(see the last tab of the Security page). Which backend is selected there?

Comment 3 Christian Esken 2004-07-16 22:43:43 UTC
Well, that is confusing - I am wondering why *my* key is needed for encryption.  Well, I bet it is actually not needed. OK, enough of the theory and back to your questions.
1) Yes, I have selected a key. It is an OpenPGP key.
2) Hmm, currently there is NO backend selected. But I can actually still select an OpenPGP key. I think that is VERY strange: No backend selected, but I have a key.

I have just tested what heappens, if I enable and then disable the OpenPGP backend. Now the key has vanished and I cannot select a new key.

I would guess that it is a configuration file migration problem. Is there a migration script that would normally run for "normal" users (those who run releases instead of CVS versions)?

BTW, "handle SIG43 nostop" should help.

(not that I know what real-time event 43 is...)
