Description Martin Airs 2010-09-16 17:58:33 UTC 
Application: kmail (2.0 beta1)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.34.6-54.fc13.x86_64 x86_64
Distribution: "Fedora release 13 (Goddard)"

-- Information about the crash:
- What I was doing when the application crashed:
I was in a mail folder and I searched for some text in the search box at the top
then I selected another mail folder while the text was still in the search box, the new mail folder showed up but the text in the search box at the top had frozen
then I opened a new tab and then there was my mail folder and an empty tab
I can close either tab and kmail will crash

The crash can be reproduced some of the time.

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

Was already fixed.
Please update your version.
Comment 2 Martin Airs 2010-09-17 01:29:50 UTC 
I'm sorry, I thought I was running the latest version, kdepim-4.4.93
were can i get the latest version from?
Comment 3 Martin Airs 2010-09-17 01:55:00 UTC 
I have just confirmed I am using kdepim 4.4.93, and actually in help->about kmail it reports version 2.0 beta1, so kmail actually reported the wrong version to DrKonqi

New crash information added by DrKonqi

kmail (2.0.89) on KDE Platform 4.5.86 (4.6 >= 20101210) using Qt 4.7.1

- What I was doing when the application crashed:

It doesn't really appear to be fixed: I got the crash in latest trunk (up-to-date as of a few days ago).

The way I triggered it was to (accidentally) middle-click on the parent folder of the folder I had open in KMail.  This opened a new tab called "Empty", displaying no emails.  When I closed this tab, KMail crashed.

Comment 5 Alex Merry 2010-12-15 12:26:55 UTC 
And I can reproduce it consistently.

>The way I triggered it was to (accidentally) middle-click on the parent folder

I can reproduce this part with kdepim master

> When I closed this tab, KMail crashed.

but not this one :)
