Bug#642433: xserver-xorg-core: crashes on pressing random keys on the keyboard while screen locked

[Michal Suchanek <michal.suchanek@ruk.cuni.cz>]

The 'Lock Desktop' key produces something very weird when pressed.

I have no idea how to reproduce on a standard keyboard:

ButtonPress event, serial 27, synthetic NO, window 0x2400001,
    root 0x151, subw 0x2400002, time 121788805, (42,35), root:(111,978),
    state 0x0, button 2, same_screen YES

EnterNotify event, serial 27, synthetic NO, window 0x2400001,
    root 0x151, subw 0x0, time 121788805, (42,35), root:(111,978),
    mode NotifyGrab, detail NotifyInferior, same_screen YES,
    focus YES, state 512

KeymapNotify event, serial 27, synthetic NO, window 0x0,
    keys:  81  0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   
           0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   0   

ButtonRelease event, serial 27, synthetic NO, window 0x2400001,
    root 0x151, subw 0x2400002, time 121789061, (42,35), root:(111,978),
    state 0x200, button 2, same_screen YES

Thanks
