Sentry Crash Report:

Description carlo.tognetti 2012-08-31 09:31:44 UTC 
Application: kmail (4.8.4)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-30-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Firs crash when I was searching for an e-mail with the internal search engine.
Then kmail crashes at every startup. Other Kontact applications (korganizer, knotes, kaddressbook) start fine 

- Unusual behavior I noticed:
Nothing

- Custom settings of the application:
-- Changed the default kde font, and the composer font, (from the debug info it seems the problem is somehow related to the fonts) but I did this many kmail startup ago.
-- Added 2 po3 accounts.
-- Added 1 freepops (http://http://www.freepops.org) account
This way it's been working fine foe a lot of times
During last execution:
-- Changed the composer font for the last sent mail
-- Added 1 more freepops (http://http://www.freepops.org) local accounts to retrieve mail from the same webmail account, but from a different folder
-- Added, in Kontact, sync to Gcal, Google accounts (sync with Android accounts) but the problem remains after disabilng the auto-retrieve feature for each e-mail account
-- Changed the kde default web browser from Rekonq to Firefox
-- Maybe I forced italian spellcheck

- I created a new account on my PC and there kmail starts fine.
- It crashes at startup even if I rename ~/.local/share/local-mail

The crash can be reproduced every time.

-- Backtrace:

Comment 1 carlo.tognetti 2012-08-31 15:53:51 UTC 
Kmail is up again. To have it start again as my user I had to:

- remove the content of (thanks to allemensen on https://bbs.archlinux.org/viewtopic.php?id=134571)
    /home/[my user]/.kde/share/apps/kmail2/
- move back to it's original path the folder local-mail (/home/[my user]/.local/share/local-mail)

At this point kmail started fine but had problems with akonadi so I restarted akonadi
- sudo akonadictl restart

and everything now is running fine.
I'm keeping a copy of the two files originally in /home/[my user]/.kde/share/apps/kmail2/autosave that were probably  cased the problem.
To me the bug still exixts, even if I've solved the problem
Comment 2 Laurent Montel 2012-08-31 16:11:22 UTC 
IF you can send me your /.kde/share/apps/kmail2/autosave/* file perhaps I can look at it.

Or perhaps it's still bug with identity.
Comment 3 carlo.tognetti 2012-09-03 14:42:24 UTC 
Laurent

  I can provide you the files, but they contain some kind of confidential data. 
So I can attach them to an e-mail if I'm sure that they'll not be published 
and that they will be used as reserved information.

I need to be sure that just you will be able to read the data, and will 
destroy them ASAP. Can you confirm?

Sorry, but I have to ask you all these boring confirmations because of both my 
country lows and our certification.

Differently I could " anonymize " the files by changing some relevant strings, 
but I think that you could better debug if you are sure that the files are 
exactly those that created the problem. 

Carlo
Comment 4 Laurent Montel 2012-09-03 15:17:52 UTC 
Of course.
Yes I will not publish them.
And destroy them after reproduce crash.

Regards
Comment 5 Christoph Feck 2012-09-03 15:30:09 UTC 
Just don't attach them to this bug, but mail Laurent directly. Otherwise the data is permanent (attachments cannot be deleted).
Comment 6 carlo.tognetti 2012-09-04 08:04:54 UTC 
Sent the content of the autosave directory directly to Laurent.
Comment 7 Denis Kurz 2016-09-24 18:22:39 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 8 Denis Kurz 2017-01-07 22:13:51 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.
