I have a MacAlley IceKey keyboard, which has F1-F15 function keys.

Using the gnome keyboard settings, I've bound F13, F14 and F15 to play/pause, previous and next track respectively. The keyboard settings app describes these keys as "Tools", "Launch5" and "Launch6".

The F14 and F15 bindings work, but the F13 binding ("Tools") does not. Binding it to a different action does not work, and binding a different key to the play/pause action does work - so it's clearly specific to this key.

using `xev`, I can see that pressing the key registers a reasonable-looking input event for "XF86Tools":

KeyPress event, serial 33, synthetic NO, window 0x1c00001,
    root 0x2bf, subw 0x0, time 3485114, (274,488), root:(1238,544),
    state 0x0, keycode 191 (keysym 0x1008ff81, XF86Tools), same_screen YES,
    XKeysymToKeycode returns keycode: 179
    XLookupString gives 0 bytes: 
    XmbLookupString gives 0 bytes: 
    XFilterEvent returns: False


This is a regression - it worked fine in Fedora 18 (gnome 3.6). I've tried disabling the shortcut and re-setting it just in case there was old config, but that didn't help.
