 SoaS build: 20090503...

 After starting a couple of programs, we notice that some of the programs
 started leave the flickering start icon in the window list. The window of
 the program is indicated with a dark circle in the bar.

 Screenshots attached: the first browse icon and the terminal icon in the
 screenshot are flickering. The actual program are accessible with the dark
 circles in the application bar.

 Reproducing this is pretty hard. It mostly happens when starting the
 bigger programs (like browse or etoys) followed by opening some others.

 When it happens, I do see the following in the shell.log:
