OK, this bug is REALLY bad!
It should be marked as highest severity.

When I use amarok randomly my PC almost "hangs".
What happens is everything stops responding. The Keyboard is 100% dead. Nothing not even caps lock works.
I can however use the mouse,(USB mouse only not touchpad). BUT with the mouse I can only click on X(to close) boxes but not yes to confirm boxes. I can right click on amarok and quit the application although music continues.

Previously I wasn't sure what was causing the problem! Now I am sure its amarok.
To fix I used to poweroff laptop and poweron.(hardware reset).
Now I have remotely ssh -ed into my PC and pgrep amarok and killall -9 amarok.
Once I did that my PC worked again perfectly.

I believe I had this problem with Amarok 1.4.2 as well.
It is so bad amarok is unusable to me.
Please help/look into this.

I am available if you need more help just Jabber/MSN me.
