Could you please upgrade to a newer Amarok version and test again? Current is Amarok 2.4.0, Amarok 2.4.1 is to be released tomorrow.

Please report back.
Comment 3 Myriam Schweingruber 2011-06-16 14:48:12 UTC 
Any news on this? Without feedback within 2 weeks I will close this as fixed.
Comment 4 Myriam Schweingruber 2011-07-16 07:49:13 UTC 
Closing for lack of feedback. Feel free to reopen if you can still reproduce
this with Amarok 2.4.2 beta 1 or later and provide the necessary feedback.
