Description markus.wallerberger 2013-01-25 16:42:44 UTC 
Application: kontact (4.9.4)
KDE Platform Version: 4.9.4
Qt Version: 4.8.3
Operating System: Linux 3.5.0-22-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
- What I was doing when the application crashed:
In KMail 4.9.4, when I select one specific e-mail in my inbox, KMail crashes. All other e-mails work fine.

The e-mail is 1.9 MiB in size and has a TeX file and a PDF file as attachments. It is in the inbox folder of an Akonadi IMAP resource linked to my GMail account. I provide a cleaned-up version of the e-mail as attachment.

- Reproducible:
Always.

- Steps to reproduce:
1. Open KMail
2. Select this e-mail in the folder view

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault

Created attachment 76716 [details]
The e-mail that causes the crash (caution: cleaned-up)

This is the e-mail that causes KMail to crash. For data protection reasons, I have replaced some headers with *********. If you need the original e-mail, please drop me a note and I will send it to you.
Comment 2 Laurent Montel 2013-01-25 17:18:55 UTC 
Save your email as mbox please.

Comment 3 Laurent Montel 2013-01-25 17:44:23 UTC 
Sorry can't reproduce it.
Perhaps I need to have initial email don't know.
Comment 4 markus.wallerberger 2013-01-29 10:17:16 UTC 
I suspect now this is related to the "Enterprise headers" in KMail ... 

If I open the e-mail in the Akonadi Console ("Browser" tab), it works fine. I can view both the formatted version in the "payload" sub-tab and the unformatted code. If I now change the message header theme to "fancy headers" or "classic headers", I can view the e-mail in KMail as well.

The weird part is though that if I now change the headers back to "Enterprise", it still works now. So now I can't reproduce it anymore either.
Comment 5 Laurent Montel 2013-01-29 14:19:16 UTC 
If you can't reproduce it too bad.
I will close until you can reproduce it.
