Description Wes D 2009-12-16 19:56:37 UTC

Application that crashed: kmail
Version of the application: 1.12.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-16-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
If my gpg key cache time expires and I switch mailboxes into a mailbox where the previously viewed email was encrypted using GPG, it will ask me for my private key password.  If I'm not interested in decrypting it, and instead want to view a different message, I hit "Cancel"; pinentry goes away.  It then shows a message showing that the email failed to decrypt, do I want to try again?  If I hit "cancel" at that point, Kmail will crash, 100%.

This looks like bug 180741. Can you check
https://bugs.kde.org/show_bug.cgi?id=180741#c41 ? Thanks

Comment 2 Wes D 2009-12-17 18:38:31 UTC

It's entirely possible.  If I disable the preview pane in Kmail prefs, the problem doesn't appear.  To clarify

-Disable preview pane
-Click on message that is GPG encrypted to my private key from a friend
-PINEntry window pops up
-I hit Cancel
-GPG Warning "Invalid Passphrase" pops up, from Kmail
-I hit Cancel
-Message window opens with standard blue markup and "Message could not be decrypted" as the message body.
-Kmail does *not* crash.

So it appears to be related to the preview pane, but I don't know enough about it to say if it's related explicitly to 180741 or 208245
