Application that crashed: kmail
Version of the application: 1.12.90
KDE Version: 4.3.61 (KDE 4.3.61 (KDE 4.4 >= 20090717))
Qt Version: 4.5.2
Operating System: Linux 2.6.27.25-0.1-pae i686
Distribution: "openSUSE 11.1 (i586)"

What I was doing when the application crashed:
While testing bug 138445
On a new testuser I start kmail, create a new mailfolder with type "mbox".
Stopping kmail and changing the permission of the mbox file to read-only.
Restarting kmail and clicking on that mbox-folder crashes kmail.
