[wmii] wmii bug ?

i use wmii-3.5.1 in Arch Linux. some times while wmii is running, it
stops takiing any actions from keyboard, i mean, it does not take any
action no matter what keys i press but in the end i can use
"C-M-backspace" to kill X and start again, eveni can do "C-M-F2" to go
to another virtual terminal but wmii itself does behaves as if
keyboard is not present, though i can move the mouse without any
problem.
