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. KDE Kontact crashed and it could not be restarted. I had to restart Ubuntu Linux in order to restart KDE Kontact. This happenned at least three times before your bug reporting software was automatically invoked.

2. I am using Ubuntu Linux 9.10, 64 bit, using an Intel Core 2 Duo CPU on an Asus K5B motherboard. I do not find such crashes ocurring when I use any version of Thunbderbird for processing mail including saving e-mail messages to the Ubuntu File browser.

3. There seem to be other serious problems with Kmail in particular. For example, it is not possible to save an e-mail message from Kmail to the Ubuntu Linux file browser without also saving attachments at the same time. It should be possible to separate messages and attachments thereto. Even after unchecking the "inline" feature and checking the "hide" feature in Kmail, the attachments coninue to be saved in the message itself.

4. I would like to use Kmail and other KDE Kontact applications because of the integrated architecture and various features. For example, the ability to select the format of the time displayed in Kmail is a VERY USEFUL and IMPORTANT feature. On the other hand, there are many features missing or that need to be improved.
