Description Milian Wolff 2011-08-25 11:45:03 UTC

Application: kmail (4.8 pre)
KDE Platform Version: 4.7.00 (4.7.0)
Qt Version: 4.7.3
Operating System: Linux 3.0-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
I started kmail and it tried to download my mails from multiple resources. Then the "sieve password" dialog for one of my dimap accounts popped up (it happens frequently - no idea why) and afterwards it crashed.

Maybe related: I have lots of filters, the ui hang a bit after accepting the sieve dialog.

After kmail crashed, my akonadi_pop3_resource crashed as well with this bt:

the kmail stuff is a hand compiled version from ~2 weeks ago, I'll update it now.

Comment 1 Laurent Montel 2011-08-25 15:21:19 UTC

Ok for the backtrace but don't understand why sieve password is asking

Comment 2 Milian Wolff 2011-08-27 02:12:53 UTC

I get that dialog quite often at startup. Sometimes I get the dialog for all my resources. Sometimes no dialog at all.

Don't ask me what's going on, but it really looks flaky...

Comment 4 Christophe Marin 2012-04-20 12:19:03 UTC

from bug 298396
- What I was doing when the application crashed:
I have setup Kontact/KMail/Akonadi to support Sieve. Kontact starts after logging in and I do not open accept the request to open KWallet by entering my password, because I am AFK. When I later come back, Kontact will have opened a window asking me for my Sieve password (and username, but that is already filled in) and the KWallet dialogue is still open. I enter my KWallet password in one dialogue and as soon as I enter the Sieve password into the other, Kontact will segfault.

The issue persists in KDE 4.8.3.

- What I was doing when the application crashed:
Same thing as last time: Using Kontact/KMail with Sieve, waiting after starting Kontact while ignoring the KWallet password dialogue, Sieve password dialogue pops up, I enter my password and Kontact crashes.

- What I was doing when the application crashed:

Same as before: KWallet password dialogue appears to have timed out, Sieve password dialogue is being displayed, I wait even longer before entering my password and Kontact crashes. This time I am using KDE 4.9.0, still with Qt 4.8.2.

Comment 9 David Faure 2012-09-19 20:45:15 UTC

I think the crash happens when "this" (the Session instance) gets deleted by some event handling that happens during the QDialog::exec() modal dialog.
Then it crashes when accessing a member variable (m_url) of "this", which is logical.

Solution 1: use a non-modal dialog
Solution 2: use Q[Weak]Pointer on "this", a common recommendation for modal dialogs nowadays.

For the record: I implemented this possible solution about 1 month ago so it should be included with KDE SC 4.9.1.  Would be interested to know if this solution works.  It was very hard for me to reproduce and I can't now -- but I'd like to hear back from others.

kontact (4.9.3) on KDE Platform 4.9.3 "release 520" using Qt 4.8.3

- What I was doing when the application crashed: Like before let kmail2 open close your session (with restore on) 
Reboot the computer, and after the login let the kwallet password opened for at least 15 minutes ... enter the password, and hit cancel on the first imap login ...
you get a crash like one year and a half.

Still present in 4.9.3

hit cancel button on the sieve login, and let kmail2 crash and drive you there...

kontact (4.10) on KDE Platform 4.10.00 using Qt 4.8.4

- What I was doing when the application crashed:

The issue persists/returned in KDE 4.10.0:

* After login, kontact was started automatically (it is usually not closed properly due to some other bug)
* There is a KWallet dialogue asking for my password, but I did not enter any
* Apparently the Sieve login timed out and thus Kontact asks for the password on its own
* I do not immediately enter a password there either
* I enter the Sieve password later and Kontact crashes with attached backtrace

Comment 19 Denis Kurz 2016-09-24 18:15:01 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 20 Denis Kurz 2017-01-07 22:16:21 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.
