Comment 1 Christophe Marin 2011-09-03 14:52:18 UTC 
Maybe dup of bug 267111.

Please install the missing debug packages to get a better backtrace please (kdepimlibs4-debuginfo & libakonadi4-debuginfo)
Comment 2 Daniel Ziltener 2011-09-04 12:19:19 UTC 
Unfortunately I can't install the debug packages because my distribution (OpenSUSE with KDE 4.7 Repo) doesn't have them... Sorry for this.

Can you try KDE:Distro:Factory ?
Comment 4 Daniel Ziltener 2011-09-10 20:18:45 UTC 
It's the computer I use daily, so I don't really like the idea of installing factory packages.

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

Kmail crashed after I selected and de-selected several imap folders in the folders pane.

Comment 8 Allen Winter 2011-12-22 21:55:19 UTC 
fyi, I suggested a possible fix for this.
see http://git.reviewboard.kde.org/r/103421/

however, the maintainer of the KSelectionProxyModel class rejected my patch.

I'll CC Steve on this bug and see if the info in here helps him figure out what's really happening.

kmail (4.8 rc2) on KDE Platform 4.7.97 (4.8 RC2 (4.7.97) "release 1" using Qt 4.8.0

- What I was doing when the application crashed:

I think this crash is related, too.

1.) Have 10+ dIMAP folders
2.) Expand all the folders in the left side of KMail
3.) Click and drag from upside-down: click on an empty area below the folders, hold the mouse button, move the mouse upwards fast
4.) and while you're doing this, on the halfway KMail will crash
