Description yannek 2011-10-15 21:52:11 UTC 
Application: kmail (4.7.2)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
After booting the computer and logging in,  kmail started automatically, new mails were found and shown per number in the icon. Upon clicking on the tray icon kmail crashed.

This happens every time on a fresh computer start if new mails are indicated and kmail is unminimized for the first time. After restarting of kmail everything works as expected.

The crash can be reproduced some of the time.

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

kmail (4.7.2) on KDE Platform 4.7.2 (4.7.2) using Qt 4.7.4

Just to be comprehensive, here a second stacktrace. The crashes still occur ranging from "always the first time" to "pretty sure always the first time".

kmail (4.7.2) on KDE Platform 4.7.2 (4.7.2) using Qt 4.7.4

- What I was doing when the application crashed:

Had just started the computer, KMail started automatically and was showing new mails. Clicked the systray icon to open KMail, crashed.

Comment 3 yannek 2011-11-23 15:02:15 UTC 
Okay, the crashes went away after I imported the old mail from the ~/Mail directory into the "new" local dir folders via the "files-> import messages" option. 

Before the mail in ~/Mail was accessed as a "kmail-maildir" resource.

The movement of the imported mails to their respective places and marking the messages as already read again caused some crashes. But now using KMail is stable.
Comment 4 Myriam Schweingruber 2012-08-18 22:08:47 UTC 
All backtraces show actually problems with Qt, not with Kmail nor Akonadi or any related technology. Is this reproducible with Qt 4.8.x?
Comment 5 yannek 2012-10-06 11:04:33 UTC 
No, with the current setup (kmail 4.8.5, Qt 4.8.1) the imports no longer crash and access to old folders seems stable.
Comment 6 Jekyll Wu 2012-10-06 11:58:12 UTC 
Thanks for your feedback. Close this report for now.
