Bug 211803

Application that crashed: kmail
Version of the application: 1.12.2
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-14-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I opened a message from the sent-mail folder in a separate window and wanted to delete one of attached jpeg images. Right-clicked the attachment and selected to remove it from the message. Then warning about invalidating digital signature followed, pressed delete, but the message wan not deleted. After second attempt to delete this attachment kmail crashed.
