Ubuntu 9.10 seems to be forgetting my keyboard preferences - or more specifically one setting in particular.

I am altering the repeat keys delay slider in keyboard preferences and it is being saved, but some time later, I keep noticing it has returned to its default setting - I cant put my finger on exactly when it is however... Entering the keyboard preferences shows the slider where I left it - ie it has not returned to its default value, and if I touch the slider again but hardly move it, the setting I want is again restored.

Pretty annoying to have this setting resorting to its default all the time, anyone else come across this?
