Wrong Key-Syms are stored in the Settings dialog für XF86 Keys

[ezechiel]

When using the System-Settings dialog to configure Shortcuts using additional keys that result in XF86xxx Keysyms the keysyms are entered wrong.

I am using a Microsoft Ergonomic Keyboard 4000 and was wondering why the calculator did not work. The reason for this failure applied to all XF86-Keysyms (for example: keysym 0x1008ff49, XF86Launch9)

For example:
To start the system calculator you would press the calculator key; this key will result in the following output from xev:

KeyRelease event, serial 37, synthetic NO, window 0x5000001,
    root 0xc3, subw 0x0, time 4286723, (57,76), root:(1977,128),
    state 0x10, keycode 148 (keysym 0x1008ff1d, XF86Calculator), same_screen YES,
    XLookupString gives 0 bytes:
    XFilterEvent returns: False

Controlling the value in the keyboard-settings dialog only "Calculator" is seen in the assigned value for starting the calculator.
Controlling the value in dconf-editor shows the same result.

Now when I change the value from Calculator to XF86Calculator in dconf-editor the calculator works again.

This behavior exists for every shortcut based on the XF86-keys when they are assigned via the settings-dialog
