Bug 237633

Application: kmail (1.99.0)
KDE Platform Version: 4.4.75 (KDE 4.4.75 (KDE 4.5 >= 20100505)) (Compiled from sources)
Qt Version: 4.7.0
Operating System: Linux 2.6.33.3-custom i686

-- Information about the crash:
- What I was doing when the application crashed:

Checking my email and changing from one folder to another. I changed from one folder to another clicking on the name of the folders.

- Unusual behavior I noticed:

After crashing, the output in konsole was:

kmail(1392) KMMoveCommand::execute: AKONADI PORT: Disabled code in   virtual KMCommand::Result KMMoveCommand::execute()
kmail(1392) KMMainWidget::updateMessageActions: Fix enable/disable send_queued action 
kmail(1392) KMReaderWin::setMessage: void KMReaderWin::setMessage(const Akonadi::Item&, MessageViewer::Viewer::UpdateMode) QSplitter(0x8ca1bb0, name = "splitter2")
kmail(1392) MessageList::StorageModel::messageForRow: Not a message -1 "" "" 
ASSERT: "mail" in file /usr/local/kde4/src/KDE/kdepim/messagelist/storagemodel.cpp, line 292
*** KMail got signal 6 (Crashing)
KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = kmail path = /usr/local/kde4/bin pid = 1392
KCrash: Attempting to start /usr/local/kde4/lib/kde4/libexec/drkonqi from kdeinit
sock_file=/home/morphbr/.kde4/socket-wakko/kdeinit4__0


Also the process stays there and I need to kill "by hand" in order to be able to start KMail2 again.

- Custom settings of the application:

IMAP account using GMail

The crash can be reproduced every time.
