FS#640 - E segfaults when pressing power button + keyboard keys

If you press the power button (which shows a menu option in E to close computer) and extremely-fastly you press any keyboard key, you got a segfault

This can help making it to appear: cd /tmp ; mprime-cpu -t
Also if you add a “drop caches” on that command should help too, giving you more human-time over computer-time

<PrinceAMD> what i think is happening here is
<PrinceAMD> an object is deleted, then a key pressed on the object causes seff
<PrinceAMD> so i think some check is needed in _e_manager_cb_key_down
<PrinceAMD> i'm guessing this is a keybinding bug, so lets say the binding trigger a call of a deleted pointer,
