Version: 1.8 (using KDE 3.4.0, compiled sources) Compiler: gcc version 3.3.5 (Debian 1:3.3.5-8) OS: Linux (i686) release 2.6.9-1-686 If I set my KDE language to something other than C, and go to KMail Settings, Composer, Text, and press the Add button and select en_US, the settings are forgotten (sometimes) once I close the window, and always on next startup. If I select another language, not even en_US, it also fails.
