Description Baokai Lei 2012-11-25 15:37:57 UTC

Application: kmail (4.9.3)
KDE Platform Version: 4.9.3
Qt Version: 4.8.3
Operating System: Linux 3.5.0-19-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:

I've just added a new Smtp server in KMail and set it to remember the password. Confirming the dialog, a KWallet dialog appeared, asking me if I want to allow KMail to access KWallet. Upon clicking "Always allow", KMail crashed.

This is using the latest KMail 4.9.3 from the Kubuntu ppa on Kubuntu Quantal Quetzal.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault

Comment 2 Laurent Montel 2013-02-05 19:04:29 UTC

What did you do ?
Do you start from empty config ?
etc.

Comment 3 Eugene 2013-02-05 19:11:19 UTC

That's right. First I configured IMAP, saved settings and then configured SMTP and after pushing save button it crashed.

Comment 4 Denis Kurz 2016-09-24 18:14:18 UTC

This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present?

If noone confirms this bug for a Framework-based version of kmail2 (version 5.0 or later, as part of KDE Applications 15.12 or later), it gets closed in about three months.

Comment 5 Denis Kurz 2017-01-07 22:12:26 UTC

Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
