After composing an email and pressing the send now button, Kontact crashes without sending the email. This does not occur everytime, so it is possible to still send out email.

I also tried sending mail out just using kmail and not kontact and there is no problem, so I believe the crash occurs in kontact itself.

This also occurs when replying to an e-mail.

This is the backtrace I get:
