Application that crashed: kontact
Version of the application: 4.3.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-16-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
1. Before the crash occurred, I had copied some folders from one Kmail directory to another Kmail directory that I had just created.

2. I then opened the one of the directories that I had just copied. KDE Kontact then failed and the the KDE Crash reporting program was automatically invoked.

3.   I was running KDE Kontact on Ubuntu Linux 9.10, 64 bit version using the standard desktop (not the KDE Desktop). The CPU is an Intel Core 2 Duo unit. The motherboard is model no. K5B made by Asus with 2.0 GB of memory.

4. The following applications were running on my computer system when the crash occurred:

4.1. Gnome File Browser.
4.2. KMail in KDE Kontact.
4.3. Gnome Text Editor.

 -- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
The current source language is "auto; currently c".
