Rui Matos e160babe3f keybindings: Avoid using unitialized memory and grabbing random keys 
meta_parse_accelerator() considers 0 length accelerator strings as
valid, meaning that the keybinding should be disabled. Unfortunately,
it doesn't initialize the MetaKeyCombo so if the caller doesn't
initialize it either, we end up using random values and possibly
grabbing random keys.
