Bug 128403

Version:           3.5.2 (using KDE 3.5.2, Kubuntu Package 4:3.5.2-0ubuntu18 dapper)
Compiler:          Target: i486-linux-gnu
OS:                Linux (i686) release 2.6.15-23-k7

I was type a new mail in Kontact/Kmail... I then change the spellcheck language (from french (defautl) to english). I had a message box saying that the dialog had to reload... the Kontact/Kmail crashes! I tried to relaunch Kontact, crash again just after starting.
So I tried to run Kmail (alone, without Kontact) from Konsole and here the "log":
