Bug 251119

Application: kmail (1.13.5)
KDE Platform Version: 4.5.1 (KDE 4.5.1) (Compiled from sources)
Qt Version: 4.6.3
Operating System: Linux 2.6.34-gentoo-r6 x86_64
Distribution: "Gentoo Base System release 2.0.1"

-- Information about the crash:
- What I was doing when the application crashed:

1. KMail is *not* running.
2. Navigate to a website with a form that will be sent via email. Something like
<form action="mailto:info@example.org" method="POST" enctype="text/plain">…</form>
3. Fill in some fields and send the form. A composer window opens (a dialog asked if I am sure).
4. Select >Settings >Configure KMail…

instant crash

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
The current source language is "auto; currently asm".
