Version:            (using KDE 4.1.1)
OS:                Linux
Installed from:    Ubuntu Packages

The crash occurs when I launch Kontact and click on the inbox of an imap account, then click on "New Message", and then click on the text field for the body.

It doesn't crash when I compose a message without first clicking on an inbox.

Here is the backtrace:
