Pressing the decimal point on the numeric keypad of my Belgian keyboard
results in a comma instead of a point. Non-Gtk X applications, the Linux
console and Windows all produce a point for that key.

This is especially confusing in programs as Galeon and Epiphany, which use
both Gtk and Mozilla: the same key will produce different symbols in
different text boxes.

I'm using XFree86 4.2.1, and this is the keyboard section of my XF86Config:
Section "InputDevice"
        Identifier      "Generic Keyboard"
        Driver          "keyboard"
        Option          "CoreKeyboard"
        Option          "XkbRules"      "xfree86"
        Option          "XkbModel"      "pc105"
        Option          "XkbLayout"     "be"
EndSection
