[Bug 31043] Kmail crashes directly on startup

[jeroen69]

Public bug reported:
https://launchpad.net/malone/bugs/31043

Affects: kdepim kmail (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
using dapper - 3.5.1-0ubuntu2

Yesterday the kmail package and a lot of other kde packages and also the
kernel where updated. I can't open Kmail anymore.

*Opening kmail as another user is no problem
*Moving kmailrc soes not solve the problem
*Moving ~/Mail away does solve the problem. Moving it back gives the crash again.

So somehow kmail has a problem with my Mailfolder. There where never
ever any problems with my mailfolder before.

Kmail is now unusable for me, because I need those Mailfolders off-
course.
