Bug 117150

Version:           1.9 (using KDE 3.5 (RC1), Gentoo)
Compiler:          gcc version 3.3.6 (Gentoo 3.3.6, ssp-3.3.6-1.0, pie-8.7.8)
OS:                Linux (i686) release 2.6.11-gentoo-r11

It could be a duplicate of 82859, but that bug is marked as resolved, while I am still experiencing this with 3.5 rc1!

1. Open a composer window and type in something
2. Start spell checking and change language. A dialog appears saying "You have to restart the dialog for changes to take effect". Dismiss it.
3. Now, most of the time kmail crashes. Not always, however!
