** Description changed:

  Sometimes when I want switch my computer into sleep mode, it fails. When
  I click sleep mode button, the procedure normaly began, but it does not
  finish and the computer wake-up again. I think the culprit is Amarok
  (see the line 50420.600093 in the attached dmesq log bellow). When I
  terminated Amarok and tried to switch into sleep mode again, it
  suceeded.
  
+ I meet this bug for longer time. For sure it was already in kubuntu
+ 11.04. I am not sure about kubuntu 10.10.
