Bug 149682

Version:           1.9.6 (using KDE KDE 3.5.6)
Installed from:    Fedora RPMs
Compiler:          gcc-Version 4.1.1 20070105 
OS:                Linux

kmail crashes right at the beginning.

I am using Fedora Core 6 with kdepim.i386                             
6:3.5.6-0.2.fc6 = kmail 1.9.6

Starting kmail in a terminal I receive:

./kmail
QGArray::at: Absolute index 0 out of range
[uwe@uwe bin]$ KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = kmail path = <unknown> pid = 21062

I already deleted the *.index and *.ids files but that had no significant
effect. kmail reconstructs the .ids and .index files in the first level of the mail
directory and then crashes.
When I delete the kmailrc file in /home/uwe/.kde/share/config, kmail comes up and I can configure it but I can't access my mails.
