[dresnu]

Kicker crashes after some time in use in Kubuntu Feisty.

This is the information I get from the terminal:

*** glibc detected *** kicker: malloc(): memory corruption (fast): 0x080a0120 ***

Apart from the standard applications in the system tray I have the kde keyboard tool and amule running and also I use the cpu information applet called kima.

Fixed in Intrepid since Kicker is no more. (Replaced by Plasma, totally new code)
Thanks for the bug report nonetheless, and we hope you choose to contribute to Kubuntu in the future!
