Bug 73154

Version:            (using KDE Devel)
Installed from:    Compiled sources
OS:          Linux

One has to run kmail, then press the "New" button.
Now one starts typing the message, presses "Tools" "Spelling",
then changes the language dictionary.

One sees an info message box, saying:
"You have to restart the dialog for changes to take effect",
and the only thing to press is the OK button.

Here's when it crashes. Now the strange thing is if one goes to Settings, Spellchecker, then it's possible to change the dictionary, run the spellcheck with the desired dictionary and everything is fine.

Nice touch is that even though kmail crashes, the message does not get lost.

These are the two most recent entries from "rpm -q --changelog kdepim-kmail":
* Thu Jan 15 2004 Laurent MONTEL <lmontel@mandrakesoft.com> 3.1.94-30mdk

- Add patch19: "reply all" into toolbar

* Wed Jan 14 2004 Laurent MONTEL <lmontel@mandrakesoft.com> 3.1.94-29mdk

- Sync with CVS
- Fix duplicate entries

And finally this is what one gets as a backtrace on my system.
