Hi,

There's a reproducible crash (segfault) in kmail. I can reproduce it in
Debian's oldstable, stable and testing versions of kmail, so it's present for a
significant number of releases now. How to reproduce:

1) Find an email that requests a read receipt (e.g. send yourself one).
2) Click on the email. A dialog appears with the question what to do with
   this read receipt (ignore, refuse, send). Do not click any button.
3) Meanwhile, select another mail in the mailbox.
4) Only then, answer the question in the message box.

Kmail then reproducibly crashes. This happens on various types of questions /
message boxes that may pop up when reading an email, but I've found the read
receipt confirmation to be most prevalent. I've attached a stack trace
(generated on the version in Debian stable).

This actually happens to me fairly often as I have the habit to click
through a number of new emails and only notice the message box after
I've clicked on the next mail already.

Thanks.
