            Bug ID: 302983
          Severity: crash
           Version: unspecified
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: crash while clicking on mbox folder
    Classification: Unclassified
                OS: Linux
          Reporter: kollix at aon.at
          Hardware: Compiled Sources
            Status: NEW
         Component: general
           Product: kmail2

Application: kmail (4.9 rc1)
KDE Platform Version: 4.8.4 (4.8.4) (Compiled from sources)
Qt Version: 4.8.2
Operating System: Linux 3.1.10-1.9-desktop i686
Distribution: "openSUSE 12.1 (i586)"

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

I installed self compiled KDE 4.9 from current git, cleaned all .kde4 .local
.config etc. dirs from my test user and started KDE (inside a Xephyr X server).
I started kmail and got the account creation wizard in which I entered "test"
as username and "test at localhost" as mail address. Then I added an MBox resource
and selected the 68MB large mbox file in ~/Mail.tests/mbox2
When Finishing the wizard, kmail showed a progressbar in the right bottom
corner slowly increasing.
When it was at about 70% or so I clicked on the Mbox folder in the left tree ->
crash

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Aborted
