The resource leak is immediate. You can see X-Server taking resources right
away. Normally X server on my system consumes 6% average, I have many windows
opened. When an application with an animated icon is launched the X server
average would leap to 10% and it will continue to grow more and more till 100%
shortly after 100% is reached it will lock down KDE and alas - you can't even
kill xdm - only to reboot.  The time required for the complete lock down is
about 30 hours. 

It looks like that even if you close an application with an animated icon the
damage is done to the X-server, it's performance is never back to normal.

Yes, it happens with system tray icons. I could rule out KDE if you could name
any linux application which is constantly changing icons in the tray. Not like
it changes once in an hour but rather a 2-3 changes per second. 

It might be not wine problem but KDE.
